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.

Quick-Disconnect Tube Couplings for Food and Beverage
- Temperature Range:
Acetal Plastic: -40° to 180° F
Polypropylene Plastic: 32° to 160° F - Tubing:
Barbed Fittings: Use with soft or firm (Durometer 65A-80A) polyurethane rubber
Compression Fittings: Use with hard or firm (Durometer 80A-60D) nylon or polyethylene plastic - Specifications Met: NSF/ANSI 169
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.
