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

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 120 psi.

Build a compressed air system in half the time it would take to build a copper or steel system.

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

Compatible with ARO-shape plugs and sockets.

Also known as automotive couplings. Compatible with Tru-Flate-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.

Compatible with Japanese-shape plugs and sockets.

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 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.

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 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 A-shape plugs and sockets.

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.

Add quick connection points for mechanical gauges and other diagnostic equipment to your line. These couplings are also known as test ports and diagnostic couplings.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Couplings consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are designed for coolant applications up to 200 psi. Also known as coolant-line mold couplings.

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.

Couplings are compatible with quick-disconnect Plastic-shape plugs and sockets. They are designed 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 100 psi.

Minimize spills if a driver pulls away from your diesel exhaust fluid (DEF) pump too soon. Both halves of these couplings have a shut-off valve that stops the flow they’re separated.

For frequent connections, this hose has a socket end that's faster to connect and disconnect than a threaded fitting. Thanks to two layers of blended rubber, this hose bends twice as sharply and resists wear and tear 80 times better than our basic hydraulic hose.

Convert dispensing tips with male threads into quick-disconnect couplings.

These rigid tip adapters penetrate gaskets, sealed bearings, and joints to deliver grease to precise locations.

These flexible extensions have a quick-disconnect fitting that snaps into your dispensing tip, so you can lubricate grease fittings that are hard to reach.
