The PRO-SOURCE 90341100809 is a one-piece CPVC pipe flange sized for 4-inch pipe with slip end connections. Flanges of this type are used to terminate a piping run at equipment, valves, or bulkhead penetrations, creating a bolted, gasketable joint that can be disconnected for service. Constructed from chlorinated polyvinyl chloride (CPVC), this fitting handles the elevated temperatures and corrosive media common in industrial and commercial plumbing systems. At 3.67 pounds, the one-piece design eliminates the split-flange assembly step and provides a uniform sealing face. Plumbers and pipefitters install this fitting using solvent cement into a standard 4-inch CPVC slip socket.
This flange is suited for commercial and industrial piping systems where CPVC is specified for chemical resistance or higher-temperature service. Typical applications include process piping, chemical feed lines, and hot-water distribution systems. The slip connection style accepts standard 4-inch CPVC pipe directly, making it compatible with Schedule 40 and Schedule 80 CPVC pipe systems that follow standard dimensional tolerances. It is not intended for use with PVC or CPVC threaded fittings in place of a slip connection without modification.
Designed as an OEM-style replacement or new-installation fitting for 4-inch CPVC piping systems using slip-connect solvent-cement assembly methods.
Installation should be performed by a licensed plumber familiar with CPVC solvent-cement procedures and applicable codes such as the IPC or ASTM F439 standards for CPVC fittings. Shut off and depressurize the piping system completely before cutting into an existing line. Use only CPVC-rated solvent cement and primer; do not use PVC-only cement on CPVC fittings. Allow full cure time per the cement manufacturer instructions before returning the system to service or torquing flange bolts.
