Attach these chains to cam-and-groove couplings to keep compatible plugs and sockets together.

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.

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.

Metal hose fittings have better durability than plastic barbed hose fittings.

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.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

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.

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

Each of these metal fittings is double bagged to prevent contamination in areas that require a high level of cleanliness.

Built with ball bearings, these fittings continuously swivel 360° before and after installation to prevent your hose from twisting, kinking, and failing. They’re made of 316 stainless steel, so they won’t corrode from a wide variety of chemicals, as well as fuels, gasoline, and oil.

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 10,000 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 High-Pressure Minimal-Spill-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.

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

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 nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

Couplings consist of a plug and a socket that connect more quickly than threaded garden hose couplings. To connect, push the plug into the socket. The compact design makes these couplings sleeker and easier to handle than cam-and-groove garden hose couplings.

Use these barbed fittings in low-pressure steam applications up to 150 psi. Slide the barbed end into hose and secure with a clamp.

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

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

Fittings have a barb that grips onto tubing. Use in applications up to 150 psi.
