Joininglargerdiameterpipingsystems,particularlyforpres-

installation technique is critical. Close attention to the steps
below will help professional mechanics to complete success-
ful installations.
8. Join Pipe and
Fittings
• Assemble pipe
and fittings quick-
ly while cement is
fluid. If cement
has hardened, cut
pipe, dispose of
fitting and start
over.
• Insert pipe into
the fitting hub

giving a quarter turn as the pipe is being inserted, ensur-
ing an even distribution of the cement within the joint.
Do not quarter turn the pipe after contact with socket
bottom.

• Seetableforrecommendedsetandcuretimes.
• Removeexcessce-
ment from the ex-
terior. A properly
made joint will
show a continuous
bead of cement
around the pe-
rimeter. If voids
appear sufficient
cement may not
have been applied
and joint failure
may result.

1. Cut Pipe
• Cut pipe square
with the axis. All
joints are sealed
at the base of the
fitting hub. An
angled cut may
result in joint
failure.
• Acceptable tools
include recipro-
cating saw, me-
chanical cut off saw with carbide tipped blade or other
appropriate tool.

2. Remove Burrs
and Bevel
• Remove all pipe
burrs from inside
and outside diam-
eter of pipe with a
de-burring tool.
• Chamfer (bevel)
the end of the pipe
10° - 15°. Pow-
ered and manual
chamfering tools
are available.
3. Clean and Dry
Pipe and
Fittings
• Remove surface
dirt, grease or
moisture with a
clean dry cloth.

Primers and cements are extremely flammable and may
be explosive. Do not store or use near heat or open
flame, or death or serious injury may occur.
• Solvent fumes created during the joining process are
heavier than air and may be trapped in newly installed
piping systems.
• Ignition of the solvent vapors caused by spark or flame
may result in injury or death from explosion or fire.
• Read and obey all manufacturers' warnings and any
instructions pertaining to primers and cements.
• Provide adequate ventilation to reduce fire hazard and
to minimize inhalation of solvent vapors when working
with cements, primers and new piping systems.
• Align all piping system components properly without
strain. Do not bend or pull pipe into position after being
solvent welded.
