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.

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.

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

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

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.

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

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.

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

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

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

Typically used with low-pressure stainless steel threaded pipe fittings.

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

Typically used with standard-wall aluminum unthreaded pipe fittings.

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

Thick walls give these Schedule 80 fittings excellent strength.

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

Also known as Pressure Class 200 pipe.

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

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.

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

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.
