1/2 In. Sweat X 1/2 In. D Sweat Copper Union 1 Pk

A union fitting joins two copper pipes and allows them to be disconnected for repairs without cutting the pipe. This Nibco 633-W copper union is essential for plumbing maintenance and repairs, letting you service a line or replace a damaged section. The center nut holds the joint together and can be loosened to separate the pipes when needed, making it ideal for water supply lines in homes and commercial buildings.

Constructed from wrought copper, this union combines durability and corrosion resistance in a compact, reliable design. The solder cups on each end accept standard 1/2 inch copper pipe and are soldered in place using heat and solder. Once installed, the union provides a permanent connection that can be disassembled for future service—eliminating the need to cut and resolder pipe when repairs are required.
