Industrial Quick-Disconnect Hose Couplings for Air
A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. They are also known as industrial interchange couplings. All Industrial plugs are compatible with any of the Industrial sockets of the same coupling size, regardless of the pipe size or barbed hose ID.
Plugs are also known as nipples. Plugs and sockets with a clamp-on/crimp-on barbed end insert into rubber hose and secure with a clamp or a crimp-on hose ferrule. 303 stainless steel has very good corrosion resistance, so it’s the best choice for high-humidity environments.
NPTF (Dryseal) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Open-Flow Quick-Disconnect
Hose Couplings for Air and Water
Couplings allow for maximum flow because there’s no shut-off valve in the plug or the socket. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All Open-Flow plugs are compatible with any of the Open-Flow sockets of the same coupling size, regardless of the pipe size. They are compatible with Hansen ST, Parker ST, and Perfecting E couplings.
Plugs are also known as nipples.
303 stainless steel plugs and sockets have very good corrosion resistance. They’re the best choice for high-humidity environments.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
Warning: There is no valve in these couplings. Stop the air and water flow before you disconnect the line.

Quick-Disconnect Couplings for Plastic Tubing—Gasoline
- Tempearture Range: 0° to 150° F
- Tubing: Use with firm (Durometer 45D) polyethylene or polypropylene plastic, except fittings with male threaded pipe connection
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 and remove the plug. Plugs and sockets are 316 stainless steel for excellent corrosion resistance.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so gasoline won’t spill 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 have a sleeve (ferrule) that bites into the tubing and forms a seal when you tighten the nut.
