Iron and Steel Pipe and Pipe Fittings

Low-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

Use in low-pressure applications up to 285 psi.

High-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

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

Medium-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

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

Extreme-Pressure Steel
Threaded Pipe and Pipe Fittings

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

Iron and Steel Unthreaded
Pipe and Pipe Fittings

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

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

Iron and Steel Pipe
Fittings with Flanged Ends

testString

Bolt the flanged end of these fittings to another same-size flange, pump, or valve with a gasket to create an access point in a pipe line.

Other Steel Pipe Adapters

Low-Pressure Clamp-On Connectors

Low-Pressure Clamp-On Connectors

Use in low-pressure applications up to 20 psi.

Right-Angle Flow
Rectangular Manifolds

Tube Fittings for Steel Tubing

Fittings have fair corrosion resistance. They are more economical than other metal tube fittings.

Hose Fittings

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