Universal style couplings, also known as “Chicago Couplings” or “Air King”, are most commonly used on hose lines connecting pneumatic tools to a compressed air source. Firmly pressing one coupler to another and twisting seals the connection. Safety clips prevent accidental disconnection during use. A convenient quick connect system to mate varying diameters of hose as all sizes up to 1 inch are interchangeable. Sizes over 1 inch have a four lug design. Universal couplings do not interchange with sandblast, Minsup, or European style couplings of similar design.
