MEGALUG: THE PRODUCT OF PREFERENCE SINCE 1984
Since 1984, engineers and contractors designing and installing
water and wastewater pipelines and systems have come to rely
on the EBAA Series 1100 MEGALUG Mechanical Joint Restraint
as the “Product of Preference” for effectively and economically
restraining ductile iron pipe connections above or below ground.
MEGALUG Mechanical Joint Restraints replace external restraints such as cumbersome concrete thrust blocks and corrodible metal tie rods creating a quicker, safer and more economical
installation.

Major testing laboratories agree as the 3” through 24” sizes
are Underwriters Laboratories (UL) listed, and the 3” through 12”
sizes are Factory Mutual (FM) approved.
For use on all classes of ductile iron pipe (PC350 through
PC150 and CL56 through CL50), for practically any application
including valves, hydrants and pipe, the MEGALUG Mechanical
Joint Restraint effectively and safely performs without damage to
the pipe or cement linings.

The wedge style MEGALUG design reacts
to the amount of force acting on the joint.
When each wedge is set, the wedge teeth
penetrate the pipe’s outer surface, and
the wedge does not move on the pipe.
There is very little change in this interface
until the wedge movement begins inside
the pocket of the main casting. Once the
wedge starts moving, the formation of the
buttress begins.
This “dam” of material (the wedge
impression) is cold formed as the wedging
action continues. If the force of pressure
acting on the joint is released, the wedge
moves back to near its original position.
This engages the reserve-controlled movement or “RCM”. The wedge is then ready
for another round.
After the wedge has moved to the back

of the pocket at the maximum pressure or
load, the wedge buttress are in shear. The
maximum movement is about 0.3 inch
through the thirty-six inch size and 0.4
inch for forty-two and forty-eight inch.
The RCM is available even with severe

cyclic loads. This has been tested to very
high-pressure differentials and the wedge
impressions look the same as if a single
test had been performed.
Typically, the depth of pipe wall penetration, or wedge impression at around
25,000 pounds of force per wedge (200
PSI on a six inch and 150 PSI on a twelve
inch) is 0.03”. Finally, at roughly twice that
force the penetration is around 0.05” At
these high pressures, there is no affect on
the design thickness of ductile iron pipe
made according to AWWA C150. The lack
of damage to the cement lining clearly
indicates that the thrust load is primarily
longitudinal.
This ability to move in the pocket allows
for angular flexibility as well as longitudinal flexibility.

THE ORIGINAL PATENTED
GRIPPING WEDGES
Since 1964 EBAA Iron has responded
aggressively to the needs of the
water industry for better solutions
to joint restraint problems - thus the
development of the family of self
actuating MEGALUG wedge action
restraints.
TOOLS
MEGALUGS install using an ordinary
wrench (box, ratchet, or air-driven),
because the torque-limiting, twistoff nuts automatically shear during
tightening when the proper torque
is reached. The same 1¼ wrench
used to tighten the T-bolts on the
4” through 24” sizes can be used
to tighten and shear the twist off
nuts in all sizes. If removal becomes
necessary, a 5/8 hex head remains
so the screws can be loosened, and
retightened with a torque-indicating
wrench. During removal, the wedges
are held in place by retainer clips.
DEFLECTION
The MEGALUG gripping wedges
provide resiliency to your
pipeline design. In addition
to deflecting as much as

allowed by the
mechanical joint
during installation,
it can also deflect
after assembly:
Sizes of 12” and below
are capable of up to 3
degrees of deflection after
installation (depending on the
preset deflection.)
The 14” and 16” sizes are
capable of 2 degrees deflection.
The 18” through 24” sizes are
capable of 1.5 degrees deflection.
The 30” through 48” sizes are capable of
1 degree deflection.
The 54” size has a 0.5 degree deflection.
STEEL PIPE
The 1100 Series MEGALUG can be used to restrain
3” - 8” SCH 40 or 80 steel pipe when joining to
mechanical appurtenances. It can also be used on
steel pipe in all sizes if the pipe’s outside diameter is
the same as the ductile iron pipe and its thickness is
equal to or greater than PC350 ductile iron pipe in sizes
of 16 inch and below and PC250 ductile iron pipe 18
inches and above.
CAST IRON PIPE
Grey iron pipe diameters are often larger than ductile
iron pipe diameters. The Series 1100 MEGALUG
restraint may be used with grey iron pipe having
standardized cast iron O.D. per AWWA C150 and
C151, and with pit cast Classes “A” and “B”
without modification. Use of the Series 1100
with pit cast grey iron Classes “C” and “D”
will require over sizing the MEGALUG. More
information on this is explained in detail in
“Connections Bulletin DI-1”.

MEGALUG
Takes the Load
On April 11, 1997 EBAA Iron performed a remarkable force demonstration of their series 1100 MEGALUG Joint
Restraint. With the use of EBAA’s Series 1100 MEGALUG using a standard
mechanical joint installation on 12 inch Ductile Iron Pipe, and a 80 Ton motor crane, EBAA Iron lifted a D7 Caterpillar Track Type Tractor weighing in at
50,350 lbs. Along with this, the Series 1100 MEGALUG has been tested to over
700 PSI. Concluding that EBAA’s MEGALUGS can take the load.

2.

1. The Series 1100 MEGALUG joint

restraint is designed for use on
ductile iron pipe conforming to
ANSI/AWWA C151/A21.51 (all
thickness classes) when restraining
mechanical joint pipe fittings.

2. Clean the socket and the plain
end. Lubrication and additional
cleaning should be provided by
brushing both the gasket and the
plain end with soapy water or an
approved pipe lubrication meeting

4. (cont.)

5. Tighten the bolts to the normal
range of torque as indicated [3
inch 45-60 ft-lbs., 4-24 inch 7590 ft-lbs., 30-36 inch 100-120
ft-lbs., and 42, 48 and 54 inch
120-150 ftlbs.] While at all times
maintaining approximately the
same distance between the gland
and the face of the flange at all
points around the socket. This
can be accomplished by partially
tightening the bottom bolt first,
then top bolt, next the bolts at
either side, finally the remaining
bolts. Repeat the process until all
bolts are within the appropriate
range of torque. In large sizes (3048 [and 54] inch), five or more
repetitions may be required. The
use of a torque-indicating wrench
will facilitate this procedure.

3.

4.

the requirement of ANSI/AWWA
C111/A21.11, just prior to slipping
the gasket onto the plain end for
joint assembly. Place the gland on
the plain end with lip extension
toward the plain end, followed by
the gasket.
NOTE: In cold weather it is
preferable to warm the gasket
to facilitate assembly of the
joint.

5.

6. Tighten the torque limiting twist
off nuts in a clockwise direction
(direction indicated by arrow
on top of nut) until all wedges
are in firm contact with the pipe
surface. Continue tightening in an
alternating manner until all of the
nuts have been twisted off.

3. Insert the pipe into the socket and
press the gasket firmly and evenly
into the gasket recess. Keep the
joint straight during assembly.
4. Push the gland toward the socket
and center it around the pipe with
the gland lip against the gasket.
Insert bolts and hand tighten
nuts. Make deflection after joint
assembly but before tightening
bolts.

6.

7. If removal is necessary, utilize
the ⅝ inch hex heads provided. If
reassembly is required, assemble
the joint in the same manner as
above, by tightening the wedge
bolts to 90 ft-lbs. If the series 1100
restraint is removed from the pipe,
be sure that all the collar bolts and
wedges are in place before the
restraint is reassembled.
Steps 2-5 are requirements of
AWWA. AWWA Standard C600
