Brass Quick-Disconnect Tube Couplings for Air
- Temperature Range: 0° to 150° F
- Tubing: Use with hard polyethylene plastic or polypropylene plastic, except straight sockets
An all-brass body gives these quick-disconnect couplings better durability than plastic quick-disconnect couplings. They have a chrome plating for excellent protection in corrosive environments. Couplings consist of a plug and a socket (sold separately) that join with a latch, so you can easily connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch and remove the plug.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so air won’t leak from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.
For technical drawings and 3-D models, click on a part number.
Compression plugs and sockets have a sleeve (ferrule) that compresses the tubing and forms a seal when you tighten the nut.

Through-wall sockets are also known as bulkhead sockets and panel mount sockets; they mount through your wall or panel to create an inlet or outlet.
High-Pressure Quick-Disconnect Tube Couplings for Air
Not only do these chrome-plated brass couplings have excellent corrosion resistance, they also withstand pressures up to 250 psi. Couplings consist of a plug and a socket (sold separately) that join with a latch, so you can frequently connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch on the socket and remove the plug.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so air won’t leak from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

- Temperature Range: -40° to 180° F
- Tubing: Use with firm or hard (Durometer 85A-60D) nylon plastic or polyethylene plastic
