The interior and exterior are polished to a high-luster finish to resist particle buildup and allow for easy cleaning.

When your application does not require a smooth interior, this tubing is an economical choice.

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 fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings.

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 at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

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

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

Typically used with thin-wall stainless steel unthreaded pipe fittings.

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

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

Typically used with extreme-pressure stainless steel unthreaded pipe fittings.

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.

Use these heavy duty forged flanges for high-pressure applications.

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

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

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

Typically used with thin-wall aluminum unthreaded pipe fittings.

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

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

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

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

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

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

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.

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