PRIMER
It is recommended that Tetrahydrofuran (THF) be used
to prepare the surfaces of pipe and fi ttings for solvent
welding. Do not use water, rags, gasoline or any other
substitutes for cleaning PVC or CPVC surfaces. A chemical
cleaner such as MEK may be used.
CEMENT
The cement should be a bodied cement of approximately
500 to 1600 centipoise viscosity containing 10-20% (by
weight) virgin PVC material solvated with tetrahydrofuran
(THF). Small quantities of dimethyl formamide (DMF)
may be included to act as a retarding agent to extend
curing time. Select the proper cement; Schedule 40
cement should be used for Schedule 40 pipe. Never use
all-purpose cements, commercial glues and adhesives or
ABS cement to join PVC or CPVC pipe and fi ttings.
APPLICATORS
Select a suitable pure bristle type paint brush. Use a proper
width brush or roller to apply the primer and cement (see
chart below). Speedy application of cement is important
due to its fast drying characteristics. IMPORTANT NOTE:
A dauber type applicator should only be used on pipe sizes
2 in. and below. For larger diameter pipe, a brush or roller
must be used.

A. Cutting
Pipe must be squarely cut to allow for the proper
interfacing of the pipe end and the fi tting socket
bottom. This can be accomplished with a miter box
saw or wheel type cutter Wheel type cutters are not
generally recommended for larger diameters since
they tend to fl are the corner of the pipe end. If this
type of cutter is used, the fl are on the end must be
completely removed.
NOTE: Power saws should be specifi cally designed to
cut plastic pipe.
