All Japanese plugs are compatible with any of the Japanese sockets, regardless of the pipe size or barbed hose ID. Plugs and sockets are zinc-plated steel, which is strong and durable. They have fair corrosion resistance, so they should be used primarily in dry environments.
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. They are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
Plugs and sockets with a barbed end insert into plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
