Twist-Claw Hose Couplings for Air and Water
Also known as Chicago and universal couplings, these have an identical claw-style head that allows you to connect to another Chicago twist-claw hose coupling, regardless of the pipe size or barbed hose ID. To connect, push two couplings together with a quarter twist. Couplings have a safety clip and lanyard to prevent accidental disconnection.
Iron couplings are stronger and more durable than other metal couplings. Use in noncorrosive environments. Zinc-plated steel couplings have fair corrosion resistance and should be used primarily in dry environments. 316 stainless steel couplings have excellent corrosion resistance. They’re the best choice for high-humidity environments.
Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.

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.
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.
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.
