The B&K 164-137HC PVC Union is a high-performance plumbing fitting designed for secure, leak-resistant connections in cold-water pressure systems. Constructed from heavy-duty Schedule 80 white PVC, this union is engineered for durability, chemical resistance, and ease of maintenance in both residential and commercial applications.

Featuring female iron pipe (FIP) threaded ends, the union allows for quick disassembly and reassembly of piping systems without the need for cutting or solvent welding. The integrated EPDM O-ring seal ensures a watertight connection, while the robust PVC body resists corrosion, impact, and temperature fluctuations. This union is compatible with both Schedule 40 and Schedule 80 PVC piping, making it a versatile solution for a wide range of plumbing systems.
