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

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

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.

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

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

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.

For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. Also known as KF, QF, and NW fittings, they’re used for high-vacuum applications such as vacuum coating and heat treating, leak testing, and analyzing gases.
