Move bulk material, exhaust gas, or suck up dust in powerful vacuum systems—this tubing is large enough to transfer pellets and debris and strong enough to withstand nearly perfect vacuum. Made of aluminum, it’s lighter weight than steel tubing, so it’s best when you need to reduce the weight of your system. It also resists corrosion from frequent rinsing, humidity, and rain.

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.

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

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

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.

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs.

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.

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.

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

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

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.

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.

Made of EPDM, the gasket on these fittings stands up to the hot water found in heat exchangers and cooling systems. These fittings have stainless steel pipe threads, which are more durable than the plastic pipe threads found on other push-to-connect tube fittings.

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

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

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

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

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.

Connect hot food and beverage lines with just a push. Also known as instant fittings, they have an internal gripping ring and an O-ring that hold tight to tubing.

More flexible than rigid stainless steel tubing, this hose allows you to link high-vacuum components that are misaligned. Also known as bellows. Equipped with a claw-clamp (ISO-K) fitting on each end, this hose connects to large components with fittings starting at trade number 63.

Also know as pump connectors, hose is sized to specific lengths for attaching to pumps.

Transfer harsh chemicals while reducing vibration that could damage pumps or other equipment.

The fittings are also known as an instrumentation fittings. They have two sleeves (double ferrules) that bite into metal tubing for a strong seal.

The Yor-Lok fitting is also known as an instrumentation fitting. It has two sleeves (double ferrules) that bite into metal tubing for a strong seal.

Sealed vacuum insulation and a reflective barrier inside this hose maintains the temperature of liquids as cold as -325° F. Similar to a thermos, this prevents heat transfer, so the exterior of the hose won’t freeze or form condensation. The tube stems on each end slide into tube fittings on a freezer or other equipment in your plant or laboratory.

Eliminate sharp bends at the end of your air and water hose—these fittings have a built-in kink absorber.

Fittings are metal for better durability than plastic barbed hose fittings. They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

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

Plugs and sockets are color coded by shape so you can't mix hose lines. Only plugs and sockets of the same color will fit together.

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.

Made of stainless steel, these hose fittings are more durable than plastic barbed hose fittings and have excellent corrosion and chemical resistance. Slide the barbed end into hose and secure with a clamp.

Built with ball bearings, these fittings continuously swivel 360° before and after installation to prevent your hose from twisting, kinking, and failing. They’re made of 316 stainless steel, so they won’t corrode from a wide variety of chemicals, as well as fuels, gasoline, and oil.

With just a vise and a wrench, make or repair hose assemblies in the field.

Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line.

Use these couplings at pressures up to 3,000 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 Pioneer-shape plugs and sockets.

Couplings consist of a plug and a socket that connect quickly. Use them if you need frequent access to a line. They are designed for low-pressure steam applications up to 300 psi.

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

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

Use in medium-pressure applications up to 230 psi.
