Plastic Quick-Disconnect Tube Couplings for Air and Water
Lighter in weight than their metal counterparts, these quick-disconnect couplings are plastic. They consist of a plug and a socket that allow you to frequently connect and disconnect your line.
Latch-lock sockets disconnect by pressing the latch.
Acetal plugs and sockets are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments. Plug and Sockets with shut-off have a valve to stop the flow when the coupling is separated, so air or water won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

Brass Quick-Disconnect Tube Couplings for Air
- Temperature Range: 0° to 180° F
- Tubing: Use with hard polyethylene plastic or polypropylene plastic
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 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.

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. They’re made of FDA-approved materials, including moisture-resistant plastic that won’t absorb liquid and lose strength, even in high-humidity food and beverage applications.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so fluid won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.
