Cutting
CPVC can easily be cut with a ratchet cutter, a wheel-type plastic tubing cutter, a power saw or a fine toothed saw. Tools used to cut CPVC must be designed for plastic use and must be in good condition in accordance with the tool manufacturer’s recommendations. It is important to cut the pipe square. A square cut provides the surface of the pipe with maximum bonding area.
NOTICE
Avoid splitting the pipe when using ratchet cutters. Failure to do so may result in pipe failure or leakage.

• Only use ratchet cutters at temperatures of 50°F (10°C) or warmer.
• Only use well-maintained, good quality ratchet cutters capable of consistently cutting the pipe squarely.
If any indication of damage or cracking is evident at the pipe end, cut off at least 2 in. (50 mm) beyond any visible crack.
De-burring and Beveling
Burrs and filings can prevent proper contact between pipe and fitting during assembly, and must be removed from the outside and the inside of the pipe. A chamfering/reaming tool or a file is suitable for this purpose. A slight bevel (approximately 10° to 15° by 1/8 in. to 3/32 in.) shall be made at the end of the pipe along the outer diameter to ease entry of the pipe into the socket. This will also minimize the chance that the edges of the pipe will wipe solvent cement from the fitting socket during the insertion of the pipe.
Solvent Cement Application
• CAUTION
Prior to using TFP-500 or TFP-600 One Step Solvent Cement, review and follow all pre- cautions found on the container labels, Safe- ty Data Sheet, and Standard Practice for Safe Handling ASTM F 402. Failure to follow precautions may result in injury.
