The CAMPBELL HAUSFELD tire inflator with gauge (MP600000AV) combines an inflating gun, air chuck and pressure gauge in one convenient unit that's easy to use even one handed. A clip on design enables hands free use of the chuck while inflating tires, the pressure gauge accurately shows the amount of air in the tire from 10 to 100 psi. If a tire has been overinflated, the built-in relief valve makes deflating easy. Includes a flexible hose to make reaching tire stems easier.
