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.

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.

Originally used on satellites, rocket propulsion systems, and even Mars rovers, these fittings will handle your most challenging industrial environments. They're designed to withstand high vibration and high vacuum without generating particles that could disrupt your operation.

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.

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.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

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.

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.

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

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

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.

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.
