Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. To connect, push a plug and a socket (both sold separately) together with a quarter twist. Attach an optional locking ring (sold separately) to the socket for extra protection against accidental disconnection. All of the double grip-lock plugs are compatible with any of the double grip-lock sockets, regardless of the pipe size or barbed hose ID. Plugs and sockets are zinc-plated steel, which is strong and durable. They have fair corrosion resistance, so they should be used primarily in dry environments.

Sockets have a spring-loaded locking sleeve that automatically locks into place when you connect the coupling. To disconnect, slide the locking sleeve back and twist the coupling apart.

Sockets with a barbed end insert into rubber hose and secure with a clamp or a crimp-on hose ferrule.

NPTF (Dryseal) threads are compatible with NPT threads.

Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.
