This coupling has a Male Nation Pipe Thread (NPT) on one end to mount to an air compressor or other pneumatic devices. The other end is a twist-lock, quick-connect, universal crowfoot fitting that connects to a barbed crowfoot fitting on the air hose end. These crowfoot fittings are also known as Jackhammer or Chicago-Style Universal Hose Couplings.
Chicago-style universal hose couplings are predominantly utilized for air and water applications, but not steam. We offer more 2-lug and 4-lug carbon steel couplings such as the Female NPT Crowfoot Fitting and Chicago Coupling. Universal couplings are sealed by pressing together and twisting a quarter turn. Universal hose couplings connect pneumatic and hoses to compressed air supplies.
