Crowfoot Air Hose Connector

Chicago-style universal hose couplings are used for air and water applications, not steam. These couplings are also called jackhammer or crowfoot couplings. All couplings up to 1" have a two-lug design and connect with one another. Universal couplings are sealed by pressing together and twisting a quarter turn. Universal hose couplings connect air tools and hoses to compressed air supplies.
