Permanently seal unthreaded holes in pneumatic and hydraulic components.

Give open-ended standoffs a finished look and protect them from dirt and debris.

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.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

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

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.

Made of stainless steel, these couplings stand up to wet environments.

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.

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

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

Also known as Code 61 SAE hydraulic flanges, these let you create an access point in a high-pressure hydraulic line.

Also known as ANSI flanges.

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.

The male threads on these fittings have a sealant applied for extra leak protection.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

When space is at a premium choose these compact fittings.

Use these retaining caps to secure the ends of quick-release pins in holes that are oversized or out of round.

Use a screwdriver to install these receptacles in a threaded hole.
