Milton® 1/2-Inch FNPT Brass Ball Valve | 400 PSI Full-Port Air Shut-Off Ball Valve for Compressor Tank & Shop Air System

The Milton Full-Port Brass Ball Valve gives instant, positive shut-off of an air line with a simple quarter-turn of the lever. Open it for full flow or close it to isolate a tool, drop, or section of the system for service, all without bleeding down the entire compressor. The full-port brass body passes maximum airflow with almost no pressure drop and is rated to 400 PSI, so tools downstream get the volume they need on 1/2-inch FNPT line. A brass body and stem stand up to constant shop air pressure and repeated operation, sealing tight in both open and closed positions. Use it as a tank shut-off, drop-leg isolation valve, or manifold on-off across automotive shops, fabrication floors, fleet maintenance, and industrial production lines, wherever you need reliable manual control of an air line. Supplied individually for shops and fleets that keep their air systems maintained. Backed by a 1-year limited manufacturer warranty for dependable daily service. Keep one on hand so a failed valve never takes the compressor out of service. Milton has set the pneumatic hardware standard for professional shops for decades.
