Description
Milton Type Air Quick Couplings (also known as Industrial Interchange Type couplings) are designed for compressed air and pneumatic systems that require frequent connection and disconnection. These couplings are fully interchangeable with Milton “M” Style, ARO 210, and ISO 6150-B standards. They offer secure locking, long life, and high air flow with minimal pressure drop — making them ideal for industrial rubber and PAC hoses in workshops, garages, and manufacturing plants.
