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.
Couplings with a barbed end insert into rubber hose and secure with a clamp.
Brass couplings are softer than other metal couplings, so they’re easier to thread together. They have good corrosion resistance. Warning: There is no valve in these couplings. Stop the flow of air and water before you disconnect the line.
