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.

Compatible with ARO-shape plugs and sockets.

Compatible with Schrader-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.

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.

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

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.

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 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.

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

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.

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

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

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.

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

Couplings can handle pressures up to 250 psi.

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

These brass couplings have good corrosion resistance.
