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.

Connect your hose to a cam-and-groove vapor recovery valve.

Made of plastic, these fittings are lighter in weight than metal barbed fittings, yet have the chemical and corrosion resistance to stand up to harsh substances. Slide the barbed end into plastic or rubber hose and secure with a clamp.

Made of tough Buna-N rubber, this hose has the durability to stand up to gasoline, fuel oil, and other petroleum-based products.

A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.
