More

Pipe, Tubing, Hose, and Fittings

Low-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

testString

Use in low-pressure applications up to 285 psi.

Extreme-Pressure Steel
Threaded Pipe and Pipe Fittings

testString

Use in extreme-pressure applications up to 10,000 psi.

High-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

testString

Use in high-pressure applications up to 6,000 psi.

Medium-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

testString

Use in medium-pressure applications up to 1,400 psi.

Iron and Steel Unthreaded
Pipe and Pipe Fittings

testString

Pipe and fittings weld together for a permanent connection that is stronger and less likely to leak than threaded and clamp-on connections.

Iron and Steel Clamp-On
Pipe and Pipe Fittings

testString

Pipe and fittings connect with a clamp, so they can be taken apart as needed for maintenance and repair.

Hose Fittings

Hose Fittings

Connect these fittings to lengths of hose. Hose fittings are typically used in high-flow, suction, and hydraulic applications.
