Metal Pipe and Pipe Fittings

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

testString

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Low-Pressure Stainless Steel
Unthreaded Pipe Flanges

testString

Bolt two same-size flanges together with a gasket to create an access point within a pipe line.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Low-Pressure Iron and Steel Threaded Pipe Fittings

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

Standard-Wall Steel Threaded
Pipe Nipples and Pipe

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

Low-Pressure Galvanized Iron and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Standard-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Low-Pressure Steel Unthreaded Pipe Flanges

testString

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

Butt-Weld Fittings for Stainless Steel Tubing

Butt-Weld Fittings for Stainless Steel Tubing

testString

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.
