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.

Compatible with Schrader-shape plugs and sockets.

Compatible with Lincoln-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.

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.

A slim body allows these couplings to fit into tight spaces. Compatible with Compact-shape plugs and sockets.

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.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

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.

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.

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.

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.

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

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.

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.

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

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.

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

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.

Fittings have good corrosion resistance.

Barbs grip onto tubing.

Barbs grip onto tubing.

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

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

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

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.

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

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

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

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

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

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.

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

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

Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F.

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

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

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

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.
