The B&K 164-133HC PVC Union is a precision-engineered plumbing fitting designed to provide a secure, leak-resistant connection between two sections of pipe. Made from Schedule 80 white PVC, this union is built for strength, chemical resistance, and long-term reliability in both residential and commercial plumbing systems.

Featuring female iron pipe (FIP) threaded ends, this union allows for easy disassembly and reassembly without cutting or solvent welding, making it ideal for systems requiring routine maintenance or modular assembly. The integrated EPDM O-ring ensures a watertight seal, while the corrosion-resistant PVC body withstands harsh environments and fluctuating temperatures. This union is compatible with both Schedule 40 and Schedule 80 PVC piping, offering versatility across a wide range of applications.
