General Information

 A General Information
A.1 DESCRIPTION
O-Rings offer the designer an efficient and economical sealing element for a wide range of static or dynamic applications.
Inexpensive production methods and its ease of use have made the O-Ring the most widely used seal.
A broad range of elastomer materials for both standard and special applications allow the O-Ring to be used to seal practically all liquid and gaseous media.
O-Rings are vulcanized in molds and are characterized by their circular form with annular cross section. The dimensions of the O-Ring are defined by the inside diameter d1 and the cross section d2 (Figure 1).

ADVANTAGeS
Compared with other sealing elements, the O-Ring has a wide range of advantages:
- Simple, one-piece groove design reduces hardware and design costs
- Compact design allows smaller hardware - Easy, failsafe installation reduces risk - Applicable to a wide range of sealing problems: static,
dynamic, single- or double-acting - Wide compound choice for compatibility with most fluids - Ex-stock availability of many sizes worldwide for easy
maintenance and repair

Cross sections of approximately 0.35 mm (0.014 inch) to 40 mm (1.575 inch) and inside diameters up to 5,000 mm (196.850 inch) and more are available.

A.2 APPLICATIONS

O-Rings are used as sealing elements or as energizing

d2

elements for hydraulic slipper seals and wipers and thus cover

a large number of fields of application. There are no fields of

industry where the O-Ring is not used. From an individual seal

for repairs or maintenance to a quality assured application in

aerospace, automotive or general engineering.

The O-Ring is used predominantly for static sealing

applications:

- As a radial static seal, e.g. for bushings, covers, pipes,

d1

cylinders, rods.

- As an axial static seal, e.g. for flanges, plates, caps.

Figure 1: O-Ring dimensioning

O-Rings in dynamic applications are recommended only for moderate service conditions. They are limited by the speed and the pressure against which they are to seal:
- For low duty sealing of reciprocating pistons, rods, plungers, etc.
- For sealing of slowly pivoting, rotating or spiral movements on shafts, spindles, rotary transmissions leadthroughs, etc.

O-RING � General Information
A.3 METHOD OF OPERATION
O-Rings are double-acting sealing elements. The inital squeeze, which acts in a radial or axial direction depending on the installation, gives the O-Ring its initial sealing capability. This force is superimposed with the system pressure to create the total sealing force, which increases as the system pressure increases (Figure 2). Under pressure, the O-Ring behaves in a similar way to a fluid with high surface tension. The pressure is transmitted uniformly in all directions.

Technical Information

 B Technical Information
 B.1 Materials

B.1.1 ELASTOMERS
Equipment manufacturers and end users expect sealing systems to operate leak-free over a long service life. Reliability is crucial to effective low maintenance-cost operations. To find the perfect sealing solution in each individual case, both material performance and seal design are critically important. One of the most used material groups for seals are the elastomers. Compounds can be chosen according to the properties required, such as elasticity or chemical resistance.

The following tables provide a summary of the various elastomer material groups. Trelleborg Sealing Solutions can offer a large number of materials within each group.
If no particular specifications are given for the material, standard NBR (Nitrile Rubber) in 70 Shore A will be supplied (see chapter B.1.5 Standard materials).

B.1.2 APPLICATION PARAMETERS OF ELASTOMERS

Elastomers, as all other organic chemicals, have limited use. External influences such as media, oxygen or ozone, as well as pressure and temperature, will affect the material properties and therefore their sealing capability.

Elastomers can swell, shrink or harden and develop cracks or even tears. Figure 3 and Figure 4 illustrate the performance of various elastomers under different application parameters.

Chemical compatibility For the pre-selection of a suitable material group, a comprehensive chemical compatibility guide is available. This can be downloaded from our website www.tss.trelleborg.com or you can contact your local Customer Solution Center for further details.
It is important to recognize that when using this guide, the ratings shown are based on published data and immersion tests. These tests are conducted under laboratory conditions at room temperature predominantly and may not adequately represent conditions in the field. Relative short term laboratory tests may not pick up all the additives and impurities which may exist in long term service applications.
Care must be taken to ensure that all aspects of the application are considered carefully before a material is selected. For example, at elevated temperatures some aggressive fluids can cause a much more marked effect on an elastomer than at room temperature.
Physical properties, as well as fluid compatibility, need to be considered. Compression set, hardness, abrasion resistance and thermal expansion can influence the suitability of a material for a particular application.
It is recommended that users conduct their own tests to confirm the suitability of the selected material for each application.
Our experienced technical staff can be consulted for further information on specific applications.

B.1.3 CHARACTERISTICS AND INSPECTION OF ELASTOMERS

Hardness One of the most frequently named properties regarding polymer materials is hardness. Even so, the values can be quite misleading.
Hardness is the resistance of a body against penetration of an even harder body of a standard shape at a defined pressure.

Shore A
1.25 � 0.15 mm 0.049 � 0.006 in.

Shore D
1.25 � 0.15 mm 0.049 � 0.006 in.

There are two procedures for hardness tests regarding test samples and finished parts made out of elastomer materials:

1.Shore A / D in accordance with ISO 868 / ISO 7619-1 / ASTM D 2240 - Measurement for test samples
2.Durometer IRHD (International Rubber Hardness Degree) in accordance with ISO 48 / ASTM 1414 and 1415 - Measurement of test samples and finished parts
The hardness scale has a range of 0 (softest) to 100 (hardest). The measured values depend on the elastic qualities of the elastomers, especially on the tensile strength.
The test should be carried out at temperatures of 23 �2 �C (73.4 �2 �F) - not earlier than 16 hours after the last vulcanization process (manufacturing stage). If other temperatures are being used this should be mentioned in the test report.
Tests should only be carried out with samples which have not been previously stressed mechanically.
Hardness tests in accordance with Shore A / D The hardness test device Shore A (indentor with pyramid base) is a sensible application in the hardness range 10 to 90. Samples with a larger hardness should be tested with the device Shore D (indentor with spike).
Test specimen: Diameter min. 30 mm (1.181 inch) Thickness min. 6 mm (0.240 inch) Upper and lower sides smooth and flat
When thin material is being tested it can be layered to ensure a minimum sample thickness is achieved, up to a maximum of 3 layers. All layers must be at minimum 2 mm (0.080 inch) thick.

0.79 � 0.01 mm 0.031 � 0.0004 in.

Figure 5: Indentor in accordance with Shore A / D

Hardness test in accordance with IRHD The test of the Durometer in accordance with IRHD is used with test samples as well as with finished goods.

The thickness of the test material has to be adjusted according to the range of hardness. In accordance with ISO 48, there are two hardness ranges:

Soft: Normal:

10 to 35 IRHD

 Sample thickness

10 to 15 mm (0.394 to 0.591 inch)

procedure "L"

over 35 IRHD

 Sample thickness

8 to 10 mm (0.315 to 0.394 inch)

procedure "N"

Sample thickness

1.5 to 2.5 mm (0.059 to 0.098 inch)

procedure "M"

The hardness determined with finished parts or samples can vary from those determined from specimen samples, especially those with a curved surface.

Vertically Carried Pole

The measurement is done at five different places at a defined distance and time.

Thickness of test samples (mm/in.)

With equivalent material characteristics of the elastomer sample 3, the indentor penetrates the deepest at the surface (Figure 8) and therefore establishes the softest area.

As the convex geometry has a stronger effect on smaller width O-Rings, the tolerances on hardness for widths under 2.0 mm (0.079 inch) should be increased up to +5 / -8 IRHD based on the valid IRHD nominal value.

Compression set An important parameter regarding the sealing capability is the compression set (CS) of the O-Ring material. Elastomers when under compression also show permanent plastic deformation (Figure 9).

The compression set is determined in accordance with ISO 815 as follows:

Standard test piece:
Deformation: Tension release time:

Cylindrical disc, diameter 13 mm (0.512 inch) and height 6 mm (0.236 inch) 25% e.g. 30 minutes

Where

h0 = Original height (cross section d2) h1 = Height in the compressed state h2 = Height after tension release

The accuracy of the measured value depends on:

h0

- Test sample thickness

- Deformation

- Measurement deviations

Therefore the values which have been identified with the test

sample cannot be transferred onto the finished part. The

result of the measured finished parts are strongly influenced

by geometriy and measurements as well as the measuring

accuracy of the test equipment.

B.2.2 Methods of installation and design of seal housing
Methods of installation O-Rings can be used in components in a wide variety of ways.

Installation
Incorrect without lead-in chamfer
Figure 13: Rod installation with O-Ring

During the design stage, installation must be taken into consideration. In order to avoid damage during installation, it should not be necessary to pass the O-Ring over edges or bores. When long sliding movements are involved, the seal seat should be recessed if possible, or the O-Rings arranged so that they only have to travel short distances during installation to reduce risk of twisting.
Radial installation (static and dynamic) Inner sealing (rod sealing): The O-Ring size should be selected so that the O-Ring outside diameter (d1 + 2*d2) is at least equal to or larger than the groove outside diameter d6 (Figure 14).

Manual installation -- Use tools without sharp edges
-- Ensure that the O-Ring is not twisted, use installation aids to assist correct positioning

Outer sealing (piston sealing): The O-Ring size should be selected so that the inside diameter d1 is equal to or smaller than groove diameter d3 (Figure 14).

-- Use installation aids wherever possible -- Do not over stretch O-Rings -- Do not stretch O-Rings made out of cord at the joint
Installation over threads, splines etc. Should the O-Ring have to be stretched over threads, splines, keyways etc., then an assembly mandrel is essential. This mandrel can either be manufactured in a soft metal or a plastic material without burrs or sharp edges.

Axial installation (static) During axial-static installation, the direction of the pressure should be taken into consideration when choosing the O-Ring size (Figure 15). With internal pressure, the O-Ring should be chosen so that the outside diameter of the O-Ring is equal to or larger than the outer groove diameter d7. With external pressure, the O-Ring inside diameter is chosen to be smaller than the inner groove diameter d8.

Automatic installation Automatic O-Ring installation requires good preparation. The surfaces of the O-Rings are frequently treated (see the SealGlide�- Reducing Friction with Nanoscale Treatments brochure). This offers a number of benefits during installation by:
-- Reducing installation forces
-- Eliminating stick effects, easy removal
The handling and installation of dimensionally unstable components requires a great deal of experience. Reliable automated installation therefore requires special handling and packing for the O-Rings.
Please contact your local Customer Solution Center for more information.

Technical Information

B.2.3 ELONGATION - OUTSIDE DIAMETER INTERFERENCE

Radial Installation, piston and rod sealing, static and dynamic If the O-Ring is used as a piston seal (outer sealing), the nominal O-Ring inside diameter d1 (see Figure 14), should be stretched between 2% and 5% for dynamic applications and between 2% and 8% for static applications.
For O-Rings with a diameter d1 smaller than 20 mm (0.787 inch), this is not always possible, so the stretch range is wider. To minimize this range and the maximum stretch, it is necessary to minimize the tolerances of the housing diameter d3 (see Figure 14), and have a less stringent requirement for the minimum O-Ring stretch. In dynamic applications, it is important to keep the maximum stretch to 5% or less to avoid detrimental effects on sealing performance. Exceeding these values will result in too great a decrease in the O-Ring cross section which can affect service life.
If the O-Ring is used as a rod seal (inner sealing), the O-Ring outside diameter (d1 + 2*d2) should be at least equal to or larger than the housing (groove) outside diameter d6 (see Figure 14), to give interference on the outside diameter. The O-Ring outside diameter shall not exceed 3% of the housing outside diameter for O-Rings with a diameter d1 greater than 250 mm (9.843 inch), or 5% for O-Rings with a diameter d1 smaller than 250 mm (9.843 inch).
For O-Rings with a diameter d1 smaller than 20 mm (0.787 inch), this is not always possible due to tolerance issues and can result in a greater outside diameter interference. Exceeding these values will result in too great an increase in the O-Ring cross section which can affect the service life of an O-Ring.
Axial installation, static If the O-Ring is used as a static axial seal, the direction of the pressure should be taken into consideration when choosing the O-Ring size (Figure 15). If the O-Ring is pressurized, the groove should be designed so that, prior to the pressure being applied, the O-Ring is in contact with the groove wall that is away from the side that is pressurized.
If there is external pressure, the O-Ring should be chosen so that the inside diameter d1 of the O-Ring is approximately 1% to 3% smaller than the inner groove diameter d8.
If there is internal pressure, the O-Ring should be chosen so that the outside diameter (d1 + 2*d2) of the O-Ring is equal to or larger (at most 1 to 2%) than the outer groove diameter d7.
Care should be taken with large O-Rings with inside diameters greater than approximately 50 mm (2 inch). The absolute

outside diameter interference should be evaluated and minimized to avoid the O-Ring bending and slipping out of the groove during assembly. In addition, the ratio between inside diameter and cross section and the O-Ring material should be taken into consideration. If in doubt, please contact your local Customer Solution Center.

Reduction in O-Ring cross section through elongation When an O-Ring is stretched, its cross section is reduced and flattened, and when installed in the housing, its cross section is no longer circular. The percentage that the cross section is reduced depends on the percentage S, that the inside diameter is stretched.

The percentage cross sectional reduction R resulting from diametric stretch for an O-Ring whose inside diameter is stretched between 0% to 3% (inclusive) is calculated in accordance with the following equation:
R = 0.01 + 1.06 � S - 0.1 � S2 [%]

The percentage cross sectional reduction R resulting from diametric stretch for an O-Ring whose inside diameter is stretched more than 3% but less than 25% is calculated in accordance with this equation:
R = 0.56 + 0.59 � S - 0.0046 � S2 [%]

For piston applications, the percentage stretch S is calculated in accordance with:

) S = d3 - d1

� 100 [%]

d1

) )

with d3 = housing inside diameter for piston applications.

For rod applications, the percentage stretch S is calculated in accordance with:

) S = d5 - d1

� 100 [%]

d1

with d5 = rod diameter.
Example: For an O-Ring whose inside diameter is stretched 2% the effective percentage cross section reduction is calculated as follows:
R = 0.01 + 1.06 � 2 - 0.1 � 22 [%] R = 1.73 %

O-RING � Technical Information

O-Ring as a rotary seal In some applications such as those with short running periods, the O-Ring can also be used as a rotary seal for sealing shafts. In this case, the following points should be observed:
In order to be able to function as a rotary seal, O-Rings must be installed in accordance with the rotary seal principle.
The rotary seal principle is based on the fact that an elongated elastomer ring contracts when heated (Joule effect). With the normal design criteria the O-Ring inside diameter d1 will be slightly smaller than the shaft diameter, and the heat generated by friction would cause the ring to contract even more. This results in a higher pressure on the rotating shaft so that a lubricating film is prevented from forming under the seal and even higher friction occurs. The result would be increased wear and a premature failure of the seal.
Using the rotary seal principle, this is prevented by the seal ring being selected so that its inside diameter is approximately 2 to 5% larger than the shaft diameter to be sealed. Installation in the groove means that the seal ring is compressed radially and is pressed against the shaft by the groove diameter. The seal ring is thus slightly corrugated in the groove, a fact which helps to improve lubrication.

B.2.4 INITIAL COMPRESSION
An initial compression of the O-Ring cross section in the groove is essential to ensure its function as a primary or secondary sealing element (Figure 16). It serves to:

- Achieve the initial sealing capability - Bridge production tolerances - Assure defined frictional forces - Compensate for the compression set - Compensate for wear Depending on the application, the following approximate values are recommended for the initial compression as a proportion of the cross section (d2):

Radial dynamic applications: Axial static applications: Radial static applications:

6 to 27% 13 to 36% 10 to 35%

The design of the grooves can be based on the guide values for the initial compression shown in Figure 17 and Figure 18. These take into account the relationship between loads and cross sections in accordance with ISO 3601-2.

Special materials are available for rotary seal applications. Trelleborg Sealing Solutions does not recommend the use of O-Rings as rotary seals. Please contact your local Customer Solution Center for further details.

Compression forces The compression forces of O-Rings vary, depending among other things, on the extent of initial compression, the material, the material hardness, the O-Ring's inside diameter and its cross section.
Figure 19 � Figure 21 show guide values for the uniform load of O-Rings taking into consideration the O-Ring's cross section, material type, material hardness and its compression.
These uniform loads can be used to estimate the total compression force to be applied for static installation of O-Rings.

B.2.5 GrOOVe FILL
It is important to consider groove fill of the O-Ring to avoid any detrimental effects on radial sealing performance. It is recommended that groove fill should not be more than 85 percent to allow for thermal expansion, volume swell due to fluid exposure and tolerance effects.
B.2.6 GENERAL TECHNICAL DATA
O-Rings can be used in a wide range of applications. Temperature, pressure and media determine the choice of appropriate materials. In order to be able to assess the suitability of the O-Ring as a sealing element for a given application, the interaction of all the operating parameters have to be taken into consideration.
Working Pressure Static application - up to 5 MPa (725 psi) for O-Rings with inside diameter >
50 mm (1.969 inch) without Back-up Ring
- up to 10 MPa (1,450 psi) for O-Rings with inside diameter < 50 mm (1.969 inch) without Back-up Ring (depends on the material, the cross section and the clearance)
- up to 40 MPa (5,801 psi) with Back-up Ring
- up to 250 MPa (36,259 psi) with special Back-up Ring
- Please note the permissible extrusion gaps
Dynamic application - Reciprocating up to 5 MPa (725 psi) without Back-up Ring
- Higher pressures with Back-up Ring
Speed Reciprocating up to 0.5 m/s (1.64 ft/s) Rotating up to 0.5 m/s (1.64 ft/s) Depending on material and application.
Temperature From -60 �C (-76 �F) to +325 �C (+617 �F) Depending on material and media resistance.
When assessing the application criteria, the peak and continuous operating temperature and the running period must be taken into consideration. For rotating applications, the temperature increase due to frictional heat must be taken into account.
Media With the wide range of the available materials, each with different properties, it is possible to seal against practically all liquids, gases and chemicals. Please note when selecting the most suitable material, consult the information in chapter B.1 Materials.

Radial clearance The tolerances given in Table 26 and Table 27 and the maximum permissible radial clearance S (extrusion gap) given in Table 17 and Table 18 must be maintained.
If the clearance is too large, there is a risk of seal extrusion which can result in the destruction of the O-Ring (Figure 24).

Figure 24: Radial clearance S
The permissible radial clearance S between the sealed parts depends on the system pressure, the cross section and the hardness of the O-Ring.
Table 17 and Table 18 contain recommendations for the permissible clearance S as a function of O-Ring cross section and shore hardness. The tables are valid for elastomeric materials with the exception of polyurethane and FEP/PFA encapsulated O-Rings.
For pressure above 5 MPa (725 psi) for O-Rings with inside diameter > 50 mm (1.969 inch) and above 10 MPa (1,450 psi) for O-Rings with inside diameter < 50 mm (1.969 inch) we recommend the use of Back-up Rings.

O-Rings made from polyurethane can bridge larger clearances thanks to their high extrusion resistance and greater dimensional stability. See the chapter on "Polyurethane O-Rings".

Surfaces Under pressure, elastomers adapt to irregular surfaces. For gas or liquid tight joints, however, certain minimum demands must be made on the surface quality of the surfaces to be sealed.
Fundamentally grooves, scratches, pit marks, concentric or spiral machining scores, etc. are not permissible. Higher demands must be placed on dynamic mating surfaces than on static surfaces.
At present, no uniform definitions exist for describing the mating surfaces. In practice, the specification of the Ra value is not sufficient to permit an assessment of the surface quality. Our recommendations therefore contain amongst others various terms and definitions in accordance with DIN 4768 and DIN EN ISO 4287.

These values assume that the parts are fitted concentrically to one another and do not expand under pressure. If this is not the case, the clearance should be kept correspondingly smaller.

Trapezoidal groove The trapezoidal (dovetail) groove should only be used in special cases, such as overhead installation, in order to retain the O-Ring (Figure 25). The installation dimensions are summarised in Table 21/Table 22. The trapezoidal groove is only recommended for O-Ring cross section from 3.53 mm (0.139 inch). The inside diameter of the O-Ring results from the mean groove diameter minus the cross section.

Rectangular groove A rectangular groove is preferred for all new designs. Designs with bevelled groove flanks up to 5� are permissible. If Back-up Rings are used, straight groove flanks are necessary.
To reduce risk of extrusion the radius r ideally should not exceed the maximum permissible radial clearance S (see Table 17 and Table 18).

C.1.2 FLATNESS AND ROUNDNESS
The flatness and roundness of O-Rings are not specified in either international O-Ring standard ISO 3601 or any other national O-Ring standards so these properties are not observed or limited during production unless specifically stated.

ROUNDNESS

Xmax d1

Generally O-Rings conforming to standard quality specifications can be assembled automatically, in some cases it can be important to specify flatness and roundness.

By implementing special process steps during production,

d2

the following equation and graphs show the possible limits in

flatness and roundness of elastomeric O-Rings.

Figure 29: Roundness tolerance Xmax

In general, the adherence to flatness and roundness depends on the material and on the dimension ratio of the O-Ring, and can be checked and approved in advance.0
FLATNESS

The roundness tolerance is calculated as follows: Xmax = (1.1*d1) + 2*d2
Not every material can be offered with these roundness tolerances. Please contact your local Customer Solution Center for further details.

The flexibility of elastomeric O-Rings can lead to deformation

during handling, such as after long storage times or when

added to a vibrating conveyor. These deformations cannot be

covered by these flatness and roundness specifications.

C.1.3 DIMENSION TOLERANCES

During vulcanization, elastomers are subject to dimensional changes due to shrinkage. The degree of shrinkage depends on the material, mold geometry and on the vulcanization process. To meet dimensional tolerances molds need to be adapted to the material to be processed.
O-Ring molds are often designed for NBR 70 Shore A materials. If other materials are produced with these molds, they may exhibit different dimensional tolerances due to the different shrinkage rates.

For all other dimension ratios the flatness tolerance must be requested seperately.
Not every material can be offered with these flatness tolerances. Please contact your local Customer Solution Center for further details.

To guarantee high, constant quality levels, it might be necessary to produce new or additional molds accruing extra cost.
If deviations from tolerances are acceptable, O-Rings can be produced from existing molds to avoid the cost of producing molds. This must be confirmed in writing by the customer.

The following tables show the tolerances for the inside diameter d1 and cross section d2 of O-Rings. All tolerances given are in accordance with Trelleborg Sealing Solutions standard TBS-00024 in accordance with ISO 3601-1, class B. Precision O-Rings with reduced tolerances are also available. Please contact your local Customer Solution Center for more information.

C.1.4 SURFACE QUALITY ACCEPTANCE CRITERIA
ISO 3601-3 defines and classifies surface imperfections on O-Rings and specifies the maximum acceptable limits for these imperfections depending on the defined grade.
Grade N (general purpose) Grade N identifies surface acceptance criteria for O-Rings intended for general industrial use.
Grade S (special) Grade S identifies surface quality acceptance criteria for O-Rings intended for applications requiring a higher level of quality with respect to tolerances of surface imperfections,

e.g. for safety relevant components in automotive engineering.
Table 30/Table 31 define standard form and surface deviations of Trelleborg Sealing Solutions elastomeric O-Rings in accordance with the TSS standard TBS-00005, based on ISO 3601-3, grade N (general purpose).
If no quality requirements are specified with the order, O-Rings are supplied with standard specification in accordance with Table 30/Table 31.

Quality Criteria and Product Range

 C.2 Product Range
The following tables provide a summary of available O-Ring dimensions, Trelleborg Sealing Solutions part numbers and valid standards. The tables represent a guide to common dimensions with or without a valid standard but does not include a complete range of sizes, which is more extensive. Special dimensions are also available on request. Contact your local Customer Solution Center for further details.

For the dimensions given, molds generally exist for some materials. Due to different shrinkage factors of various materials, it may not be possible to process certain materials with the existing molds. To guarantee consistently high quality levels, it might be necessary to produce new or additional molds accruing extra costs.

 D.1 Isolast� (FFKM) O-Rings
Information about our Isolast� (FFKM) O-Rings are available either in our dedicated Isolast� brochure or through your local Trelleborg Sealing Solutions company.

 D.2 FEP/PFA Encapsulated O-Rings
DESCRIPTION
FEP/PFA Encapsulated O-Rings combine the resilience and sealing force of an elastomer with the chemical resistance of PTFE or FFKM. They consist of an elastomeric core of silicone or FKM with a seamless, thin encapsulation of FEP or PFA. The required elasticity, pretension and dimensional stability is provided by the elastomer core, while the seamless FEP/PFA encapsulation ensures reliable sealing and high resistance to aggressive media.
FEP/PFA Encapsulated O-Rings are primarily used in low pressure static or slow moving dynamic applications. This seal type is recommended for non-abrasive contact surfaces and non-abrasive media only. Preconditions for the use of FEP/PFA Encapsulated O-Rings are low press-in assembly forces and limited O-Ring elongation.

ADVANTAGeS
- Outstanding chemical and corrosion resistance - Reliable, cost-effective and high-performance sealing for
many critical applications

Temperature range The specified temperature ranges are limits that must always be considered in conjunction with the media to be sealed and the working pressure. The permissible continuous operating temperatures are always lower than the given upper limits.

- Broad temperature range from -60�C (-76�F) to 260�C (500�F), depending on core material choice
- Perfect suited for use in the food, chemical and pharmaceutical industries
- Physiologically safe (can be sterilized) - Low permeation rate - Low friction coefficient prevents adhesion or stick-slip effects
(self-lubricating, smooth surface) - Excellent for high purity processes due to low leach-out - Good resistance to pressure, deformation and compression - Square and rectangular cross section are available on
demand

Figure 37: Temperature range
Gas permeability FEP/PFA encapsulations have a much lower gas permeation rate than most other plastics. Highly corrosive gases usually don't chemically attack the FEP/PFA encapsulation, but may eventually permeate through and damage the elastomer core. In general, permeation increases with temperature, pressure, and surface contact area and decreases with increased film thickness.

DESIGN RECOMMENDATIONS
FEP/PFA encapsulated O-Rings are designed to be used in the same standard O-Ring grooves and housings as elastomeric seals.
Lead-in chamfer As FEP/PFA O-Rings are squeezed during installation, lead-in chamfers and rounded edges are necessary

Radial clearance (maximum) The maximum permissible radial clearance between the sealed parts depends on system pressure, cross section and the hardness of the O-Ring. If the clearance is too large, there is a risk of extrusion which can result in destruction of the O-Ring. The recommended values assume that the parts are fitted concentrically and do not expand under pressure.

Recommended initial compression for FEP/PFA Encapsulated

O-Rings:

- Static applications:

15 to 20%

- Dynamic applications: 10 to 15%

Rectangular groove A rectangular groove is preferred for all new housing designs. Designs with bevelled groove flanks up to 5� are permissible. If Back-up Rings are used, straight groove flanks are necessary. To reduce risk of extrusion, the radius should not exceed the maximum permissible radial clearance.

Compression force The compression force varies depending upon, for example, the extent of initial compression, material properties and O-Ring dimensions. FEP/PFA Encapsulated O-Rings with a hollow core have approximately 50% less compression force than those with a solid core.

O-RING � Special O-Rings

ASSEMBLY
Axial sealing In case of axial sealing applications, e.g. flanges, there is no need for any special precautions.
d7 d8

- Install the O-Ring immediately after warming
- Prevent bending and overstretching
- For outer sealing, position the O-Ring on the installation cone and push it firmly and constantly up the cone until it snaps into the groove. Push the resizing tool over the seal and move the tool axially.

Figure 47: Radial outer sealing - Solid grooves

Pressure from Outside
Figure 45: axial sealing
Radial sealing - split grooves Split grooves for radial piston or rod seal applications offer the same easy installation as axial sealing applications

- For inner sealing place a section of the O-Ring within the groove and work the remaining seal in place by carefully pushing the blunt end of the installation tool. Use the chamfered end of the tool to resize the seal by pushing axially.

Figure 46: Radial sealing - Split grooves
Radial sealing - solid grooves Recommendations for assembly: - Clean, if possible, lubricated housing surface - Soften the encapsulation by immersing the O-Ring in hot
water 60�- 80�C (140� - 180�F)

O-RING � Special O-Rings

 D.3 PTFE O-Rings
O-Rings in Polytetrafluoroethylene (PTFE) are closed, circular rings with annular cross section. The dimensions are - as with the elastomer O-Ring - characterized by the inside diameter d1 and the cord diameter d2 (Figure 49). PTFE O-Rings are not molded but produced by machining. The rings can therefore be manufactured in all sizes.

MATERIALS
Standard material: Virgin, unfilled PTFE (polytetrafluoroethylene), Material Code PT00
PTFE is a partially crystalline thermoplastic characterized by a very high chemical and thermal resistance. PTFE has the highest resistance to chemicals of all plastics and can be used for almost any application. It has a slightly limited resistance to molten alkaline metals, to elementary fluorine and to certain halogen materials.

The material undergoes no changes on exposure to aging, light and ozone. The water absorption rate is less than 0.01%.

d2 h

d1
Figure 49: O-Ring dimensions
ADVANTAGeS
- Very good chemical resistance, compatible with most liquids and chemicals, with the exception of liquid alkaline metals and some fluorine compounds.
- Wide temperature range from approximately -200 �C (-328 �F), up to +200 �C (+392 �F), partly even up to +260 �C (+500 �F) depending on the application
- Suitable for contact with foodstuffs, pharmaceutical and medicinal products
- Physiologically safe, can be sterilized - Low friction, no adhesion - Available for all diameters up to approximately 1,000 mm
(39.370 inch).
APPLICATIONS

DESIGN RECOMMENDATIONS
PTFE O-Rings have low elasticity. The O-Ring size should therefore be chosen to suit the nominal diameter (rod or bore) to be scaled. Installation in easily accessible axial and radial split grooves are to be preferred.
The general information on the construction, design and surfaces given for the elastomer O-Rings applies also to PTFE O-Rings.
METHODS OF INSTALLATION
PTFE O-Rings can only be stretched or compressed to a very limited extent during installation.
During installation, such as on flanges, the cold flow tendency of the thermoplastic PTFE should be taken into consideration. Under pressure, PTFE deforms plastically even in the cold state, i.e. a permanent deformation takes place. If flange seals are not tightened sufficiently to give metal/metal contact, the elastic deformation and thus the elastic tension can deteriorate.

Fields of application PTFE O-Rings are used wherever the chemical and thermal resistance of the normal elastomer O-Ring is no longer sufficient. These are primarily applications in the chemical industry, foodstuffs industry, pharmaceuticals and medical technology. PTFE O-Rings are used only as static seals, e.g. on flange connections, on covers, etc.

 D.4 Polyurethane O-Rings

TECHNICAL DATA

Polyurethane is becoming more and more widely used as a sealing material due to its exceptionally high abrasion resistance and high extrusion resistance.
The polyurethane materials from Trelleborg Sealing Solutions have a number of improved making it ideal for O-Rings and other sealing elements.
The outstanding properties of polyurethane play a major role in our Zurcon� materials.

Working pressure:

Static up to approximately 60 MPa (8,702 psi) without Back-up Ring depending on the extrusion gap Dynamic up to 25 MPa (3,626 psi)

Speed:

Reciprocating up to 0.5 m/s (1.64 ft/s)

Temperature:

-45 �C (-49 �F) up to +100 �C (+212 �F) depending on the material

Media:

Hydraulic fluids, mineral oil-based greases and air.

Polyurethane O-Rings are available in dimensions in accordance with ISO 3601-1/AS568 (see Table 63, Page 137).

MATERIALS

The dimensions are given with the inside diameter d1 and the cross section diameter d2 (Figure 51, Page 137).
ADVANTAGeS

The most important characteristics of these polyurethanes are: - High tensile strength
- Low compression set
- Very good cold flexibility

The main advantages of a polyurethane material for O-Rings compared with other elastomers are the outstanding mechanical properties: - High abrasion and wear resistance tolerates aggressive
operating conditions
- High extrusion resistance allows increased pressures or extrusion gaps
- Good mechanical properties improve service life
- Low friction reduces breakout forces on start-up
APPLICATIONS
Fields of application Polyurethane O-Rings are especially suited wherever O-Rings are subject to dynamic loads.
This can include applications in hydraulics, pneumatics and in a wide range of other critical areas. In many cases, polyurethane O-Rings are used instead of NBR in view of their high mechanical strengths.
Due to their particularly high abrasion resistance, polyurethane O-Rings are more suitable than other materials in applications where bores have to be crossed or where frequent opening and closing is demanded, e.g. plug connectors and couplings.
Polyurethane O-Rings in 70 Shore A hardness material WU7T1 can be used in applications such as pneumatics where low compression set and low friction are essential.

- Constant shear modulus even at high temperatures - Resistant to weathering and aging - High damping properties - Low gas permeability - Good hydrolysis resistance - High tear propagation resistance - Free from substances which hinder paint coverage Polyurethane materials are resistant to: Mineral oils and greases, oxygen, ozone.
Polyurethane compounds are not resistant to: Esters, aromatic and chlorinated hydrocarbons, concentrated acids and lyes.
Polyurethane O-Rings are available on request in the following grades: Polyurethane, 70 Shore A Material code WU7T1 Polyurethane, 92 Shore A Material code WU9T2 Polyurethane, 93 Shore A, Zurcon�: Material code Z22 and Z24 Polyurethane, 93 Shore A, Zurcon�: Material code Z20
Depending on the production method, Zurcon� O-Rings can have an injection point on the inside diameter. This marking is placed at a 45� angle from the flash.

DESIGN INSTRUCTIONS
The same design rules apply to polyurethane O-Rings as to other elastomer O-Rings, i.e. the same installation dimensions (groove depth, groove width), see Table 23, Page 59.
Radial clearance In view of the high extrusion resistance of polyurethane, larger clearances can be bridged with polyurethane O-Rings than with other elastomers, without the additional installation of Back-up rings.
The permissible radial clearance depends on the material, O-Ring cross section and application properties, such as the temperature.

D.5 FLExIMOLDTM O-RINGS - LARGE DIMENSIONS
Trelleborg Sealing Solutions has developed a new proprietary manufacturing technology, FlexiMoldTM, that allows the manufacture of large, high quality O-Rings without the lead time and cost associated with dedicated tooling.
Compared to conventional techniques such as the splicing of extruded cord, the FlexiMoldTM process ensures full visual and dimensional integrity. It also gives the circular form the stability of a molded O-Ring, along with its intended thermal and chemical resistance capability.
Large O-Rings are used across all process industries including: chemical and hydrocarbon, pharmaceutical, food & beverage, and electronics (in particular the production of flat panel displays).

Special O-Rings

D.7 rOUND COrD rINGS (BUTT VULCANIZeD)
Round cords are produced by butt jointing extruded round cords using a special vulcanization process. They are supplied as cut lengths. The most common materials are NBR 70 Shore A, EPDM 70 Shore A and FKM 75 Shore A. Other materials are available on request.
In contrast to mold-vulcanized O-Rings, round rings made from continuously extruded cord can be made up to any desired diameter > 50 mm (1.969 inch).
The junction point always has poorer mechanical properties than the basic material. For this reason, round cord rings should be used with caution for dynamic applications, gaseous media or vacuum conditions.
The tolerances of the cut O-Ring length are acc. to ISO3302-1 L1. For tolerances of the cross sections, d2 see the tables below.
When using round cord rings in high-vacuum applications, it is recommended to use FKM. In these cases the joint has to be manufactured to a special high-vacuum quality and has to be ordered accordingly. Please contact your local Customer Solution Center for further details.
The tolerances stated are valid for round cord rings (buttvulcanized) only and refer to the cross section. Due to the applied pressure during the vulcanization process the junction point can be thinner than the cord. In general, this has no negative effect on the sealing function.
The article number of round cord rings starts wih OV.
IMPORTANT NOTE
The mechanical properties of the joint are slightly poorer than those of the basic material.
Thus in application and testing the joint should only be stretched and must not be folded. A guiding value for the maximum bending radius at the joint is  � of the inside diameter of the round cord ring.

D.8 O-RING SURFACE FINISHING
In many cases standard elastomeric O-Rings cannot be used without a modified surface. This may be necessary to reduce friction, eliminate potential contamination of the system, mark seals, or ensure tightness in special applications.
To prevent problems, O-Rings can be surface-treated by special cleaning, treatment, coating or trimming in order to ease assembly, to ensure function and long service-life.
Depending on the desired effect, multiple high-quality surface treatments or coatings can be used.
For further details regarding surface finishing of seals please refer to the separate brochures FlexcoatTM � Frictionfree Running, FlexcleanTM � Technical Cleanliness for seals or FlexfinishTM - Finishing solution for large diameter O-Rings or contact your local Customer Solution Center.

General Information

 E General Information
Back-up Rings have no intended sealing function. Instead, as their name indicates, they are protective and supporting elements made from extrusion-resistant materials which generally have a rectangular cross section. They are installed in a groove together with an elastomeric sealing element, preferably with a corresponding O-Ring in static applications.
Due to the tight fit of the Back-up Ring in the housing, they prevent extrusion of the pressurized elastomeric sealing element into the sealing gap.

Technical Information

 G Technical Information
 G.1 Materials
Back-up Rings are manufactured from virgin PTFE as standard. In view of the unfavorable cold flow behavior of virgin PTFE, these Back-up Rings are only used for low to medium loads. For higher load requirements, filled PTFE materials (with glassfiber, bronze, carbon, etc.) have to be used. For sealing against high pressures, Back-up Rings made from specially modified thermoplastic materials are available.

For the series production of larger quantities, injection molded Back-up Rings can be manufactured, e.g. NBR 90 Shore A, FKM 90 Shore A, or thermoplastic elastomers (TPE) on request.

BACK-UP RINGS � Technical Infomation

 G.3 Design Recommendations

The recommendations for O-Rings are generally valid for the use of Back-up Rings. This applies to the groove design, surface roughness, lead-in chamfers, etc.
When the pressure is applied from one side only, it is sufficient to install a Back-up Ring on the downstream side of the O-Ring. When the seal is exposed to pressure from both sides, two Back-up Rings - one on each side of the O-Ring - have to be used.

Permissible sealing gap The use of Back-up Rings allows the service pressure and/or permissible radial clearance specified in this catalog, Part I: O-Ring, chapter B.2.7 Housing design and dimensions, to be increased.

General Quality Criteria

 General Quality Criteria
The cost-effective use of seals and bearings is highly influenced by the quality criteria applied in production. Seals and bearings from Trelleborg Sealing Solutions are continuously monitored according to strict quality standards from material acquisition through to delivery.
Production facilities are certified according to relevant quality management system standards. Depending on the requirements of the customer or market and in addition to the current ISO 9001, these locations may have further certifications: IATF 16949 for Automotive customers, EN/AS 9100 for Aerospace customers, ISO 13485 for Healthcare & Medical customers and ISO 29001 for Oil & Gas customers. This enables us to provide all market segments with the required quality standards.
Our quality policy is consistently controlled by strict procedures and guidelines which are implemented within all areas of the company.
All testing of materials and products is performed in accordance with accepted test standards and specifications, e.g. random sample testing in accordance with ISO 2859-1 AQL 1.0 general inspection level II, normal inspection.
Inspection specifications correspond to standards applicable to individual product groups (e.g. for O-Rings: ISO 3601).

Temperature The preferred storage temperature for elastomer parts is +15 �C (+59 �F) and should not exceed +25 �C (+77 �F). The products should be stored away from direct sources of heat such as boilers, radiators and direct sunlight. If the storage temperature is below +15 �C (+59 �F), care should be exercised during handling of stored products, as they may have stiffened and have become susceptible to distortion if not handled carefully.
Humidity The relative humidity should be such that, given in the variations of temperature in storage, condensation does not occur. In all cases, the relative humidity of the atmosphere in storage should be less than 70%, or if polyurethanes are being stored, less than 65%.
Light Rubber should be protected from light sources, in particular direct sunlight or intense light having a high ultra-violet content. It is advisable that any windows of storage rooms be covered with a red or orange coating or screen.
Radiation Precautions should be taken to protect stored products from all sources of ionizing radiation likely to cause damage to the products.

 Guidelines for the Storage of Polymer Products Based on ISO 2230
Many polymer products and components are stored for long periods of time before being put into service, so it is important they are stored in conditions that minimize unwanted changes in properties. Such changes may result from degradation, in which case they may include excessive hardening, softening, cracking, crazing and other surface effects. Other changes may be caused by deformation, contamination or mechanical damage.

Ozone Ozone has a particularly harmful effect on rubber. Storage rooms should not contain any equipment that is capable of generating ozone, such as mercury vapor lamps or highvoltage electrical equipment giving rise to electric sparks or electrical discharges. Combustion gases and organic vapors should also be excluded, as they may give rise to ozone via photo-chemical processes. When equipment such as a fork-lift truck is used to handle large rubber products, care needs to be taken to ensure this equipment is not a source of pollution that may affect the rubber. Combustion gases should be considered separately. While they are responsible for generating ground-level ozone, they may also contain unburned fuel which, by condensing on rubber products, can cause additional deterioration.

Packaging Unless otherwise specified in the appropriate product specification, rubber products should be enclosed in individual sealed envelopes. The packaging should be carried out in an atmosphere in which the relative humidity is less than 70%, or if polyurethanes are being packed, less than 65%. Where there is serious risk of ingress of moisture (e.g. rubber-metalbonded parts), aluminum foil/paper/polyethylene laminate or other similar means of protection should be used to ensure protection from ingress of moisture.

O-RINGS AND BACK-UP RINGS � Storage Guidelines

Deformation Rubber should be stored free from tension, compressive stresses or other causes of deformation. Where products are packaged in a strain-free condition, they should be stored in their original packaging. In case of doubt, the manufacturer's advice should be sought. It is advisable that rings of large internal diameter are formed into three equal loops so as to avoid creasing or twisting. It is not possible to achieve this condition by forming just two loops.
Contact with liquids and semi-liquid materials Rubber should not be allowed to come into contact with liquid or semi-liquid materials (for example, petrol, greases, acids, disinfectants, cleaning fluids) or their vapors at any time during storage, unless these materials are by design an integral part of the product or the manufacturer's packaging. When rubber products are received coated with their operational media, they should be stored in this condition.
Contact with metals Certain metals and their alloys (in particular, copper and manganese) are known to have harmful effects on some rubbers. Rubber should not be stored in contact with such metals except when bonded to them. They should be protected by wrapping in, or by separation with, a suitable material, e.g. paper or polyethylene.
Contact with dusting powder Dusting powders should only be used for the packaging of rubber items in order to prevent adhesion. In such cases, the minimum quantity of powder to prevent adhesion should be used. Any powder used should be free from any constituent that would have a harmful effect on the rubber or the subsequent application of the rubber.

Storage life This is the maximum period of time that a rubber product, appropriately packaged, may be stored. After this time the product is regarded as unserviceable for the purposes for which it was originally manufactured. The storage life of a rubber product is influenced by its shape and size as well as its composition. Thick products usually undergo slower changes through degradation than thinner ones.
Initial storage period This is the maximum period, starting from the time of manufacture, for which a rubber product, appropriately packaged, may be stored under specified conditions before a sample needs to be inspected or re-tested.
Extension storage period This is the period for which a rubber product, appropriately packaged, may be stored after the initial storage period, before further inspection and re-testing is necessary.
Assembly These are products or components containing more than one element, one or more of which is made of rubber. Generally it is not recommended to store elastomeric products in an assembled condition. If it is necessary to do so, the units should be checked more often. The inspection interval depends on the design and geometry of the components.
Inspection before extension storage Before any items are to be stored for an extension period, representative samples of each type should be selected for inspection at the end of the appropriate initial storage period. Inspection should be in accordance with the relevant product specification.

Contact between different products Contact between products made from rubbers of different compositions should be avoided. This includes products of the same type but differing in color.
Rubber-to-metal bonded products The metal part of rubber-to-metal bonded products should not come into contact with the rubber of other products. Preservative used on the metal should be of a type that it will not adversely affect the rubber or the bond to such an extent that it does not comply with the product specification.

Visual inspection Inspect each of the items for the following: 1. Permanent distortions, such as creases or flats. 2. Mechanical damage, such as cuts, tears, abraded areas or
delaminated plies. 3. Surface cracking when viewed under a microscope
at x10 magnification. 4. Changes in surface condition, such as hardening, softening
or tackiness.

Storage Guidelines

Assessment at the end of the initial period If, following the visual inspection procedure the items are not satisfactory, they should not be stored for an extended period. If the items are satisfactory and are stored for an extended period a record should be kept of the date initial storage began as well as the date the extended storage period began. Items stored for an extended period should be inspected and tested at, or before, the expiry of the extension storage period before they are put into service or stored for a further extended period.

Note 1: Note 2:

If the storage temperature is over or under +25 �C (+77 �F) this will influence the storage time. Storage at +10 �C (+50 �F) higher will reduce the storage time by about 50%. Storage at +10 �C (+50 �F) lower will increase the storage time by around 100%. In application areas such as aerospace the storage periods can differ from this specification. These specific storage conditions have to be agreed between the supplier and the buyer.
