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

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

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

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

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

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

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

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

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

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.

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.

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

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

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

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

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.

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