Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Also known as dry disconnects and double shut-off couplings, these have a shut-off valve in the plug and socket for minimal fluid loss when disconnecting the hose line.

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.
