This NIBCO 1/2-inch CPVC-CTS and copper transition union is designed for commercial and residential hot and cold water pressure distribution systems. It features a dual-material interface combining durable, corrosion-resistant FlowGuard Gold CPVC plastic and strong, lead-free copper. The union incorporates a slip socket connection on one end for solvent welding to CPVC tubing, and a male NPT threaded connection on the opposite end to adapt easily to metal water piping. Engineered with a three-piece removable joint design, this transition union allows for straightforward future servicing, disassembly, or maintenance without cutting the pipe. It safely compensates for thermal expansion between dissimilar pipe materials and handles a maximum working pressure of up to 400 PSI
