Cam-and-Groove Hose Couplings for Vapor Recovery
Connect your hose to a cam-and-groove vapor recovery valve. The probe inside these couplings opens the valve when connected to start recovery. They’re often used when offloading fuel.
Socket connectors are also known as C×C couplers. Socket adapters are also known as C couplers. Insert the barbed end into plastic or rubber hose and secure with a band clamp (not included). Socket-to-plug reducing adapters are also known as A×C couplers.
