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

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

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 fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

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

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Made of stainless steel, these fittings have better corrosion resistance than brass 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 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

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

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.

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

Withstanding up to 300° F, these fittings have the highest temperature rating of all our brass push-to-connect tube fittings for air and water.

Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.

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.

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 61 for use with drinking water.

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

These quick-disconnect couplings meet NSF/ANSI 169 for food equipment.

These quick-disconnect couplings mate with a sanitary stainless steel quick-clamp fitting for use in dairy lines.

Metal hose fittings have better durability than plastic barbed hose fittings.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Also known as automotive couplings. Compatible with Tru-Flate-shape plugs and sockets.

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-shape plugs and sockets.

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

Couplings have a spring-loaded locking sleeve that automatically locks into place to prevent accidental disconnection. The identical claw-style head connects to another spring-lock twist-claw hose coupling with a quarter twist.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Use these barbed fittings in low-pressure steam applications up to 150 psi. Slide the barbed end into hose and secure with a clamp.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO A-shape plugs and sockets.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Hose is PVC, so it’s light and easy to handle.

Use this neoprene hose in temperatures up to 210° F.

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation.

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools.
