The B&K 164-204 CPVC Union is a high-quality, corrosion-resistant pipe fitting designed to provide a secure and easily serviceable connection between two lengths of CPVC piping. As part of the ProLine Series, this union is engineered for both hot and cold water applications in residential and light commercial plumbing systems.

Constructed from durable CPVC (Chlorinated Polyvinyl Chloride), this union offers excellent resistance to heat, corrosion, and chemical degradation. Its solvent weld design ensures a strong, leak-free bond while allowing for future disassembly without the need for cutting pipe—making it ideal for maintenance and repair scenarios.

The union includes an EPDM O-ring for a watertight seal and complies with ASTM D2466 standards. It is NSF approved for potable water use and rated for 100 PSI at 180°F, ensuring reliable performance in demanding environments.
