About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Medium-Pressure Brass and Bronze Threaded Pipe Fittings

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings. They offer good corrosion resistance.

Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Thick-Wall Brass Threaded Pipe Nipples and Pipe

A thick wall gives this Schedule 80 pipe the strength to handle high-pressure applications. It is brass for good corrosion resistance. Pipe is seamless so it has a smooth interior for unrestricted flow.

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
