Aluminum Hose Couplings | McMaster-Carr

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

Color/Shape-Match Quick-Disconnect
Hose Couplings for Air and Water

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.

Schrader Quick-Disconnect Hose Couplings for Air

Compatible with Schrader-shape plugs and sockets.

Metal Cam-and-Groove Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Metal Cam-and-Groove Hose
Couplings with Shut-Off Valve for Water

Also known as dry disconnects and double shut-off couplings, these have a shut-off valve in the plug and socket for minimal fluid loss when disconnecting the hose line.

Metal Barbed Hose Fittings for Air and Water

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

Easy-Fit Barbed Hose Fittings for Air and Water

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.

Metal Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

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.

Snap-Tite H-Shape Quick-Disconnect
Hose Couplings for Hydraulic Fluid

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.

Barbed Hose Fittings for Steam

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

Abrasive-Material Hose Fittings

Use these fittings with sand, steel shot, and other abrasive material. They have a unique claw-style head that connects to other abrasive-material hose fittings with a quarter twist.

Tubing and Tube Fittings

Aluminum Low-Pressure Barbed
Tube Fittings for Air and Water

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Choose-a-Color Aluminum Low-Pressure
Barbed Tube Fittings for Air and Water

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.
