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

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.

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

Barbs grip onto tubing.

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

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.

These brass couplings have good corrosion resistance.

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.

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.

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 Japanese-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.

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-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.

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.

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.

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.

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Also known as headers.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.
