About Pipe and Fittings

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

Extreme-Pressure Steel Unthreaded Pipe Flanges

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges. Bolt two same-size flanges together with a gasket (sold separately) to create an access point in a pipe line. They are for noncorrosive environments.

Cap flanges are also known as blind flanges.
