About Pipe and Fittings

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

High-Pressure Steel Unthreaded Pipe Flanges

Forged for extra strength, these heavy duty flanges can withstand high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line.

Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides.

Socket-connect flanges have an internal stop that supports the pipe when welding and prevents the pipe from sliding all the way through.

Cap flanges are also known as blind flanges.
