The Milton A-Style Air Plug delivers fast, secure quick connect air hose fittings for shop and industrial air lines. Insert this air plug into any matching A-Style coupler for a positive, one-handed connection, then release to disconnect air tools in seconds without shutting off the compressor or bleeding down the air line, so tool changes never slow the job. This NPT plug threads onto 1/4-inch MNPT air lines and tools with a 1/4-inch basic flow size and handles a maximum inlet pressure of 300 PSI, delivering enough air to drive impact wrenches, air ratchets, die grinders, sanders, blow guns, and tire inflators and long hose runs without starving the tool. It is a dependable everyday choice across automotive shops, fabrication floors, tire bays, fleet maintenance, and industrial production lines. A steel body keeps the connection leak-tight through thousands of insert-and-release cycles in busy service bays and on production floors, standing up to the wear that ends the life of cheaper air tool fittings. It interchanges with matching A-Style couplers and air hose connectors, so it fits the air line fittings already in your shop. Supplied as a 10-pack, it is the practical choice for shops, fleets, and MRO buyers standardizing air fittings on one proven system. Backed by a 1-year limited manufacturer warranty for dependable daily service. Keep spares at every workstation to standardize your air line fittings. Milton created and set the pneumatic connection standard used across the industry.
