Tire Pressure Gauges 2.5" Diameter
The 2.5" diameter face on these gauges allows greater resolution than the smaller 2" face, but without taking up as much room as a gauge with a 3.5" face.
For optimum precision and long life, the needle moves back to zero as soon as the gauge is removed from the tire valve. These gauges can be converted to hold the reading if desired by adding the Compact Air Gauge Check Valve (Part No. 3228-500).
