Couplings are plastic, which is lighter in weight than metal 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.

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Made of ductile iron, these couplings are tough enough to handle sand, cement, and other abrasive solids and slurries. Use their cam-and-groove fittings to quickly connect and disconnect medium- to large-diameter hose lines.
