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.

Connect quick-clamp fittings in high-vacuum applications.

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.

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

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

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

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

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.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

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

Use at pressures up to 150 psi.

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 metal quick-disconnect couplings, these couplings are plastic.

Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic.

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.

Not only is TPU (Thermoplastic polyurethane) tough enough to handle heavy particles and cardboard fibers, the material is clear so you can monitor flow.

The strongest nonmetal duct hose we offer, this SBR (styrene butadiene rubber) hose is reinforced with yarn and has a metal spiral.

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

A smooth interior allows for unrestricted flow and makes this hose easy to clean.

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.
