Interstate Pneumatics series universal coupler accepts 1/4 in. industrial, automotive and aro style plugs. Tubular valve design provides higher flow rates over conventional blade style valves. Heat treated locking balls provide long life of wear parts. Brass construction resists corrosion and prevents sparks. These couplers are interchangeable with the Universal Standard series couplers produced by other manufacturers.
All Universal Couplers require lubrication from time to time which will greatly extend the service life. Please use light-weight tool oil, preferably Interstate Air Tool Oil, a 10 weight non-detergent oil with our Part # YL12-004.
