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.
