ARO 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. All ARO plugs are compatible with any of the ARO sockets of the same coupling size, regardless of the pipe size or barbed hose ID.
Plugs are also known as nipples.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.
Plugs and sockets with a barbed end insert into plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.
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.
Push-to-connect sockets are easier to connect than sleeve-lock sockets. Connect by pushing the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
Manifolds give you a centralized and mounted location for plugging in your air tool line.
Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Nickel-plated steel has good corrosion resistance. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. Nickel-plated brass offers better corrosion resistance than unplated brass. 303 stainless steel has very good corrosion resistance, so it’s 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.
