Power Tank Heavy Duty Tire Inflator features an easy to read 2.5 inch diameter liquid filled dial gauge with rubber shock boot gauge protection. The advantages to a liquid filled gauge are longer life, shock resistance, and higher accuracy. Other features are a tough 24 inch braided hose whip, and a European style clip. The body is a high flow design with an ergonomic thumb trigger and a side pressure release button. This tool even works as a tire pressure gauge when not hooked to a tank.
