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.

Use these rings with quick-clamp high-vacuum fittings.

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.

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

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.

Connect claw-clamp high-vacuum fittings for an airtight seal.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

The hose’s embedded metal spiral along with carbon-filled fittings divert static electricity when hose is grounded and used with a metal suction tube.

Don’t worry about crushing this hose if you step on it—it has a flexible plastic spiral that springs back to its original shape.

Position this hose in any direction and it will hold its shape.

Tough, resilient EVA (ethylene vinyl acetate) offers excellent impact resistance and is long lasting.

If your liquid contains some solid particles, this tough EPDM rubber hose can handle the extra abrasion.

A small bend radius lets this hose twist and turn to fit in cramped spaces.

A braided exterior protects this hose from abrasion and over-bending. Also known as bellows, the ribbed interior makes it flexible enough to connect high-vacuum components that aren't directly aligned.

These reducers work with any vacuum hose with the same diameter.

Hook your vacuum hose to a central vacuum system.
