The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European.

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

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. Compatible with European-shape plugs and sockets.

Compatible with Lincoln-shape plugs and sockets.

A slim body allows these couplings to fit into tight spaces. Compatible with Compact-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 an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Also known as Chicago and universal couplings, these have identical claw-style heads and connect by being pushed together with a quarter twist.

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.

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

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 ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Use these CGA fittings to connect welding hose to pressure regulators and torches.

Commonly used in low-pressure welding applications, these fittings connect downstream of your pressure regulator. Slide the barbed end into hose and secure with a crimp-on hose ferrule.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

Attach these chucks to your air hose so you can connect the hose to Schrader valves.

Hose is PVC, so it’s lighter and less cumbersome than rubber hose.

Also known as hot air blower hose, this hose stays flexible and strong as it transfers compressed air at temperatures above 300° F.

Identify your air lines by color.

An extra-strong yarn reinforcement gives this hose excellent durability to handle higher pressures than standard air hose.

Hose is polyurethane so it stretches and flexes more than nylon retracting hose.

Safely deliver compressed air to brakes in semitrucks, trailers, and other vehicles with this D.O.T. certified hose. Made of flexible nylon, it will bounce back to its coiled form even after long periods of use.

A female fitting on one end swivels until tightened, making it easy to install without rotating the entire hose.

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.

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.

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.

Made of brass, these fittings have good corrosion resistance.

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.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube 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.

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.

Barbs grip onto tubing.

Monitor flow with these clear fittings.

Barbs grip onto tubing.

Fittings have good corrosion resistance.

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

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

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Use these O-rings with brass compression tube fittings that have BSPP male threads. They create a seal on the BSPP male threads to guard against leaks.

Safe for use in your air brake line, these fittings meet Department of Transportation FMVSS 571 standards. They’ve been tested for thermal cycling, vibration, and burst pressure, so put them to work right away.

Use these to replace a damaged sleeve (ferrule) in quick-assembly compression nuts.

Lighter in weight than their metal counterparts, these compression fittings are polypropylene.

Couplings can handle pressures up to 250 psi.

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

A built-in shut-off valve stops the flow when the coupling is separated, so there’s no need to worry about air or water spilling from your line. Couplings are plastic, which is lighter in weight than metal couplings.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.
