Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

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

Compatible with Schrader-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.

These couplings consist of a plug and socket that connect and disconnect quickly. Use them if you need to frequently link and unlink welding hoses, torches, and regulators. They are also known as CGA couplings.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Use these couplings at pressures up to 7,200 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with International Standard ISO Minimal-Spill-shape plugs and sockets.

Use these couplings at pressures up to 6,500 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Snap-Tite H-Shape plugs and sockets.

Ideal for lines with rapid changes in pressure and flow, these couplings have threads that lock them together. They connect more securely than push-to-connect couplings, whose bearings wear out in high-impulse conditions.

Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line.

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.

Reduce the risk of spills near electronics when connecting and disconnecting liquid cooling lines. Also known as double shut-off couplings, these couplings have a shut-off valve on both sides that stops the flow of coolant if they’re separated.

These couplings are compatible with International Standard ISO Series B-shape plugs and sockets. They are FDA compliant, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. They consist of a plug and a socket that connect and disconnect quickly so you can frequently access your line. Use at pressures up to 220 psi.

Couplings consist of a plug and a socket that connect quickly. Use them if you need frequent access to a line. They are designed for low-pressure steam applications up to 300 psi.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

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