Optimize your tire pressure accuracy with this digital inflator gauge, made with a LCD screen measuring in increments of 0.1 PSI and backlit for better measurement reading in dark environments. This comes with a 15 inch hose and a Straight Foot Head Chuck with Lock-On Threads (dual headed, not requiring a hold on the chuck during inflation). Our digital gauges also come with a 360 degree swivel gauge (head rotates for an easy and comfortable measurement reading) and +/- 1 PSI accuracy across a range of 0-255 PSI. This turns on automatically when it detects pressure and includes an Auto-shut off feature after 15 seconds that saves on battery life. Designed with a rugged and ergonomic handle grip, shock-resistant rubber boot, and deflate button for overshot tire pressure. This provides 4 units of measurements: (PSI, Bar, kg/cm2, kPa), compared to the traditional 2 units from an analog gauge. Carbon fiber gauge face appearance with a protective rubber boot to shield against impacts. Comfort molded nylon handle with coating is incredibly durable and ergonomic. Steel inflator trigger with separate brass deflation button for quick fine tuning in case you go past your target pressure. Solid brass fittings throughout provide long-lasting performance, with 1/4" NPT female air inlet (Milton 727 plug is recommended). M style coupler and plug kit includes one 1/4" FNPT coupler and one 1/4" MNPT plug. Made up of a brass body, brass sleeve coupler and steel plug. With a 1/4" basic flow size and air flow of 40 SCFM, this coupler and plug combination has a maximum pressure of 300 PSI and a Buna-N seal.
