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

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

Compatible with ARO-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 Ring-Lock-shape plugs and sockets.

Compatible with Schrader-shape plugs and sockets.

Compatible with Japanese-shape plugs and sockets.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Couplings are only compatible with other large twist-claw hose couplings. Use with tools and equipment up to 1 1/2 pipe size.

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.

Connect these fittings to air tools for pneumatic applications.

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.

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.

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

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.

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

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

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.

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.

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.

Use at pressures up to 250 psi.

Create a push-to-connect junction in equipment with these fittings. To install, drill a stepped hole in your surface, push the fitting components into place, then insert your tubing.

Couplings can handle pressures up to 250 psi.

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

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

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

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

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Silver ions in the material help inhibit the growth of bacteria, mold, fungi, and other odor-causing microbes.

Monitor flow with these clear fittings.

Made of stainless steel, these couplings stand up to wet environments.

These brass couplings have good corrosion resistance.

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

These compression tube fittings meet Department of Transportation FMVSS 571 safety standards for air brake lines.

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

Tube supports slip inside tubing to prevent the walls from collapsing.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

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

Use these sleeves with compression nuts and fittings to create a strong seal on copper tubing.

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

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