Industrial Quick-Disconnect Hose Couplings for Air
A complete coupling consists of a plug and a socket (both sold separately or in a set) 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.
Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. 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.

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.
Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.

Quick-Disconnect Hose Couplings for Natural and LP Gas
3/8 Coupling Size | 1/2 Coupling Size | 3/4 Coupling Size | |
1 Coupling Size | 1 1/4 Coupling Size |
Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket (sold separately or in a set) that connect and disconnect quickly. All of the natural and LP gas plugs are compatible with any of the natural and LP gas sockets of the same coupling size, regardless of the pipe size. Plugs and sockets are brass for good corrosion resistance. These couplings are rated ANSI Z21.41/CSA 6.9 for use with gas fuel appliances. CSA-US and CSA Certified, they also meet U.S. and Canadian safety standards.
Plugs are also known as nipples. They have a heat-sensitive fuse that will stop gas flow in the event of a fire.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so gas won’t leak from the line. They are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.
NPTF (Dryseal) threads are compatible with NPT threads.
When couplings are not connected, add dust caps and plugs to keep contaminants out of your gas line.
Warning: Stop the flow before you disconnect the line.

Quick-Disconnect Garden Hose Couplings
Use these couplings if you need frequent access to a garden hose line—a complete coupling consists of a plug and a socket that connect and disconnect quickly. The compact design makes these couplings sleeker and easier to handle than cam-and-groove garden hose couplings. Couplings have a sleeve-lock socket. Connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.
Brass couplings have good corrosion resistance and are softer than 303 stainless steel couplings, so they’re easier to thread together. 303 stainless steel couplings are more corrosion resistant than brass couplings and have better durability than brass and plastic couplings. ABS plastic couplings offer comparable corrosion resistance to 303 stainless steel couplings, but are lighter in weight.
Couplings with shut-off valve have a valve in the socket that stops the flow of water when the coupling is separated.

Quick-Disconnect Hose Couplings for Compressed Gas
Use these couplings to quickly link and unlink welding hoses, torches, and pressure regulators. They consist of a plug and socket that are sold together as a set of two—you’ll get one right-hand connection for oxygen and one left-hand connection for fuel gas. The connections are noninterchangeable and color coded so you can’t mix lines. The male threaded ends attach to threaded welding hose, and the female threaded ends attach to a torch or pressure regulator. To connect couplings, push the plug into the socket; the sleeve on the socket has a spring-loaded lock for gas-tight connections. To disconnect, pull back on the socket sleeve and twist to release the plug. The sockets have a shut-off valve that stops the flow when the coupling is separated so gas won’t leak from the line. The sockets also have a built-in check valve to prevent gas backflow. Couplings are also known as CGA (Compressed Gas Association) couplings. They are brass for good corrosion resistance.
Couplings with left-hand threads are identified with a notch in the nut.
Note: Couplings have a CGA number that corresponds to a specific type of gas. Make sure the CGA number of the coupling matches the CGA number of your tank and other system components.

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. Note: For a complete coupling, order a plug and a socket with the same coupling size.

An all-brass body gives these quick-disconnect couplings better durability than plastic quick-disconnect couplings. They’re nickel plated for very good corrosion resistance. 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.
