CPVC Reducer Coupler

The CPVC Reducer Coupler is a straight pipe fitting designed to connect two CPVC pipes of different diameters in a single line. Manufactured from high-grade Chlorinated Polyvinyl Chloride (CPVC), it provides a secure and leak-proof transition between larger and smaller diameter pipes. Ideal for both residential and industrial piping systems, this fitting is commonly used in hot and cold water distribution lines, chemical processing systems, and industrial fluid transfer setups.
