1.) Clean the pipe ends, or the area to be fused,
by removing dirt, mud, and other debris from pipe
ends. Clean water can be used for initial cleaning
of pipe surfaces prior to scraping and isopropyl
alcohol is recommended after scraping.
2.) Check pipe for out-of-round condition. If fu-
sion area is found to be out-of-round, take appro-
priate steps to bring fusion area back within re-
quired tolerances.
3.) When installing a coupling it is necessary for
the pipe ends to have a square and even cut. This
can be accomplished by various methods. (e.g. a
blade type of pipe cutter, a wood saw and a clamp
to use as a guide, a tubing cutter, or a chain saw
without bar oil for larger pipe sizes)
4.) Identify the location of the fitting to be installed
on the pipe and mark the area with a non-greasy
marker. (See “Markers” page 4)
If installing a coupler, measure the total length of
the coupler to be installed. Make a mark (with a
non-grease marker) from the pipe end that is 1/2 the
total length of the coupler. This mark is for stab depth
purposes and will ensure that the pipe end is inserted
to the center of the coupler.
