- Temperature Range: -30° to 250° F
- Tubing: Use with firm or soft (Durometer 35A-90A) Buna-N rubber, EVA plastic, gum rubber, latex rubber, neoprene rubber, polyurethane rubber, PVC plastic or silicone rubber, except for fittings with pipe end
With no latch, these couplings have a compact design to fit in small spaces. They connect with a push and disconnect with a pull, so you can easily access your line. Couplings consist of a plug and a socket (sold separately). They have a universal connection, so the plugs will connect to any of the sockets regardless of the pipe or tube size. They are nickel-plated brass for very good corrosion resistance.
Note: For a complete coupling, order a plug and a socket.

Sockets with shut-off have a valve to stop the flow when the coupling is separated, so air won’t leak from your line.

Plastic Quick-Disconnect Tube Couplings for Air and Water
![](/prerenderstable/mvPRE/contents/gfx/imagecache/501/5012k88-k76c1-c01f-digital-master1557778869-p9@halfx_636933712070727115.png?ver=imagenotfound)
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.
Twist-lock sockets connect and disconnect with a twist and do not have a 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.

- Temperature Range: -40° to 180° F
- Tubing: Use with soft or firm (Durometer 70A-85A) polyurethane rubber
Barbed plugs and sockets insert into tubing. Those with collar do not require a clamp and limit the size of the tubing to a maximum of 1/8” OD.
