A universal coupling, also called a Chicago coupling, can allow quick and easy direct connection to your air compressor hose with a turn of its common head. You’ll also find safety clips to help provide secure attachment and rubber washers to assist in making tight seals. Malleable iron couplings can be used for air or water service. Plated ductile iron couplings self-lock. Shop Grainger today and browse this selection of universal Chicago coupling options.Close
