The tire inflator gauge makes filling tires extremely easy when using an air compressor. Instead of filling a tire by checking the pressure, adjusting, and repeating, simply press the handle of the tire inflator gauge down to fill the tire to the exact pressure you want and then release the handle, it will stop filling. Besides, the tire inflator comes with an extra inflation needle and cone inflation adapters thus can quickly inflate balls, air pillows, cushions and mattresses for your convenience.
