Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Also known as I-line fittings, these quick-clamp fittings permit easy access to your line.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

Fittings have two anti-torque rings that compress the gasket to prevent rotation and reduce particle generation in high-vibration applications.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

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

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.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

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

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.

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

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

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

Typically used with extreme-pressure iron and steel threaded pipe fittings. Also known as Schedule XXH.

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

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

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

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

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

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

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

Typically used with standard-wall aluminum unthreaded pipe fittings.

Also known as Pressure Class 200 fittings.
