About Pipe and Fittings

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

Iron and Steel Threaded Pipe and Pipe Fittings

Low-Pressure Iron and Steel Threaded Pipe Fittings

testString

Use these fittings for low-pressure applications in noncorrosive environments.

FM-Approved Low-Pressure
Cast Iron Threaded Pipe Fittings

testString

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

Medium-Pressure Iron and
Steel Threaded Pipe Fittings

testString

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

High-Pressure Iron and Steel Threaded Pipe Fittings

testString

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.
