How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Double Grip-Lock Hose Couplings for Air and Water
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.

Grip-Lock Hose Couplings for Air
Also known as Bowes couplings, these consist of a plug and a socket (both sold separately) that connect with a quarter twist. They can handle higher-pressures than twist-claw couplings, and have a lower profile to fit in cramped spaces. All of the grip-lock plugs are compatible with any of the grip-lock sockets, regardless of the pipe size or barbed hose ID.
Plugs have a spring-loaded locking sleeve to prevent accidental disconnection. The sleeve automatically locks into place when you connect the coupling. To disconnect, slide the locking sleeve back and twist the coupling apart.
Plugs and sockets with a barbed end insert into plastic or rubber hose and secure with a clamp.
Zinc-plated steel plugs and sockets are stronger and more durable than other metal plugs and sockets. They have fair corrosion resistance, so they should be used primarily in dry environments. Brass plugs and sockets are softer than other metal plugs and sockets, so they’re easier to thread together. They have good corrosion resistance. 303 stainless steel plugs and sockets have very good corrosion resistance. They’re the best choice for high-humidity environments.
NPTF (Dryseal) threads are compatible with NPT threads.
Warning: There is no valve in these couplings. Stop the flow of air before you disconnect the line.
