Bolt two flanges of the same size together with a gasket to create an access point in 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. Slide the pipe into the socket and weld.

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

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

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

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

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

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 standard-wall and low-pressure stainless steel unthreaded pipe fittings.

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

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

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

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Pressure Class 6000.

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

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

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

Use these unthreaded flanges in low-pressure applications. Also known as Pressure Class 125 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.

Typically used with thin-wall aluminum unthreaded pipe fittings.

Typically used with thick-wall aluminum unthreaded pipe fittings.

Also known as Pressure Class 200 pipe.

Use at pressures up to 4,300 psi.

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.

Fittings are polished to a32 Ra and under finish on the interior.

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.
