Installation
• Cut pipe square and burr free
• Mark pipe with correct insertion depth
• Insert pipe and hand tighten
• Tighten with a wrench to the correct number of turns
Do not
• Dismantle fitting during installation
• Over insert pipe - seriously reduced joint performance
• Under insert pipe - full joint compression cannot be
guaranteed
• Overtighten
* Please note locking rings
for PE pipe shown here are
available in the PE spares kit

Seals - FPM
Finish - Black
This range uses the FPM
seals which have been
specially selected for their
ability to operate at high
temperatures. This range
is suitable for all heating
systems designed to
operate up to 105°C.
The wide range of fittings
available make PRIMOFIT
the first choice for new
installations, repair and
extension of existing
systems.
Joints are quickly made
without threads or sealing
compounds. Use the
threaded outlet tee as a
slip tee for branching off
existing pipes.
Fittings may be re-used if
the internal components
are replaced. See our
spares pack section to
renew components or
convert the fitting to a
different application.

Seals - EPDM
Finish - Galvanised
A range of couplings for

EPDM seals are suitable
for use with potable water.
The end-load couplings are
for use on galvanised steel

The non end-load
couplings may be used for
connecting and repair of all
rigid pipe materials.
We recommend that all
fittings installed below
ground should be protected
from corrosion by wrapping
with bitumastic tape.
Remember that all non

anchors of fixed points to
prevent pipe separation.
