Bronze couplings are used to join pipes, valves and fittings in plumbing, HVAC, fire sprinklers and other systems that convey liquids.

Bronze has excellent corrosion resistance for potable water and resistance to wear and deformation. Bronze couplings last longer than steel.

Common types include bronze union fittings, bronze threaded couplings, bronze flanged couplings, bronze compression couplings and bronze repair couplings.

Straight couplings, reducing couplings, 45 and 90 degree elbow couplings, tee couplings, hex couplings and ground joint union couplings.

Bronze couplings have applications in residential and commercial plumbing, fire sprinkler systems, irrigation, pumps, valves, and HVAC systems.

Bronze couplings are used to join pipes, valves and fittings made of copper, brass, bronze and sometimes steel, cast iron or PVC.

Bronze threaded and union couplings screw together. Flanged and compression couplings use gaskets and bolts or clamps for assembly.

Bronze pipe couplings are sized by the pipe inside diameter (ID) and by pipe thread size if threaded. Common sizes are 1/2 to 4 inches.

Bronze couplings that meet ASTM B16 and AWWA C800 standards conform to plumbing and mechanical codes.

Bronze threaded pipe couplings use tapered threads. Compression couplings use gaskets. Unions and flanges create metal-to-metal seals.

Bronze is suitable for pressures up to 300 psi and intermittent temperatures up to 250°F.

Apply thread sealant to bronze threaded couplings during installation. Avoid overtightening. Periodically inspect for leaks and signs of wear or damage.
