Cutting
In order to make a proper and neat joint, measure the pipe
length accurately and make a small mark. Ensure that the pipe and fittings are
size compatible. You can easily cut with a wheel type plastic pipe cutter or
hacksaw blade. Cutting tubing as squarely as possible provides optimal bonding
area within a joint.

Deburring / Beveling
Burrs and filings can prevent proper contact between tube and
fitting during assembly and should be removed from the outside and inside of
the pipe. A pocket knife or file are suitable for this purpose. A slight bevel
on the end of the tubing will ease entry of the tubing into the fitting socket.

Fitting Preparation
Using a clean, dry rag, wipe dirt and moisture from the
fitting sockets and tubing end. The tubing should make contact with the socket
wall 1/3 to 2/3 of the way into the fitting socket.

Solvent Cement Application
Use only CPVC cement or an all - purpose cement conforming to
astm - 493 or joint failure may result. When making a joint, apply a heavy,
even coat of cement to the pipe end. Use the same applicator without additional
cement to apply a thin coat inside the fitting socket. Too much cement can
cause clogged water ways.

 |
Assembly
Immediately insert the tubing into the fitting socket, rotate
the tube 1/4 to 1/2 turn while inserting. This motion ensures and even
distribution of cement within the joint. Properly align the fittings. Hold the
assembly for approximately 10 seconds, allowing the joint to set-up.

Set and Cure Times
Solvent cement set and cure times are a function of pipe size,
temperature and relative humidity. Curing time is shorter for drier
environments, smaller sizes and higher temperatures. It requires 10 to 20
minutes for perfect joint.
