Chlorinated Polyvinyl Chloride (CPVC) Unions are used to provide a method for future disassembly of piping without
cutting within buildings for potable hot and cold water distribution from the water meter to fixtures.
CPVC Unions Meet ASTM D2846 and are rated for 400 PSI at 73 degrees Fahrenheit and 100 PSI at 180 degrees Fahrenheit. CPVC Unions are NSF Listed and certified to NSF Standard 61, Annex G. Outside diameter of CPVC tubing is the same as copper tube. (CTS = Copper Tube Size) CPVC systems are accepted by all major model building codes. CPVC tubing is rated at 210° for water heater relief valve drain applications.
