Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

When space is at a premium choose these compact fittings.

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

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

Also known as Code 61 SAE hydraulic flanges.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

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

The male threads on these fittings have a sealant applied for extra leak protection.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

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

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

Also known as Code 61 SAE hydraulic flanges.

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

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.
