Typically used on small-diameter hose up to 1". To connect, push the plug into the socket. The compact design makes these couplings sleeker and easier to handle than cam-and-groove and claw hose couplings.

Typically used on medium- to large-diameter hose up to 6". To connect, insert the plug into the socket and push the levers down.

Fittings consist of a plug and a socket that connect and disconnect quickly. Use them when you need frequent access to your gas line.
