Also known as coolant-line mold couplings, these couplings are often used to install and remove coolant lines in molding and die casting applications. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the quick-disconnect coolant plugs are compatible with any of the quick-disconnect coolant sockets of the same coupling size, regardless of the pipe size or barbed hose ID.

Sockets with a shut-off have a valve that stops the flow of coolant when the coupling is separated.

Sockets 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.

Sockets with a barbed end insert into plastic or rubber hose and secure with a clamp.

Brass plugs and sockets have better corrosion resistance than zinc-plated steel, and are softer, so they’re easier to thread together.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
