Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

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

Couplings allow for maximum flow because there's no shut-off valve in the plug or the socket. Compatible with Open-Flow-shape plugs and sockets.

Compatible with Lincoln-shape plugs and sockets.

Compatible with Japanese-shape plugs and sockets.

Compatible with Ring-Lock-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.

Couplings are only compatible with other extra-large twist-claw hose couplings. Use with tools and equipment up to 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.

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.

The female connector screws directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.

Sets contain a crimping tool and a variety of CGA fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system.

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

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 built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

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.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

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

Designed for use in welding applications, these fittings are flame retardant.

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.

Made of brass, these couplings are more durable than plastic couplings.

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

Use these sleeves with brass compression nuts and fittings to create a seal on plastic and rubber tubing.

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

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

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

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation.

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

Fittings have good corrosion resistance.

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

Barbs grip onto tubing.

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.

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

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.

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

Use these nuts and sleeves with compression fittings for food and beverage to create a seal on plastic tubing.

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

Use these clamps with quick-clamp fittings for dairy to quickly connect and disconnect your line as needed.

A smooth interior reduces friction and prevents product buildup, ensuring an unrestricted flow.

Made of FDA listed materials, these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Also known as luer lock couplings, these connect with a half turn so you can easily connect and disconnect your line. With no latch, they have a low-profile design that works well in small spaces. Use in low-pressure applications up to 45 psi.

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

These brass fittings meet NSF/ANSI 372 for drinking water. They include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.
