This is the device that seals a tire puncture and inflates a flat in eight minutes. Eliminating the hassle of using a car jack and removing the tire, the unit connects to a tire valve and its compressor simultaneously pumps in air and a gel sealant to patch the hole. The gel sealant fills punctures up to 1/4" wide and the integrated pressure gauge helps determine when the tire is optimally inflated. The device is powered by a car’s DC outlet via an 11' cord that enables optimal maneuverability while a built-in light provides convenient nighttime illumination. The entire unit is as small as a shoebox and fits in the included bag for convenient storage in a trunk. Repaired tires can be driven up to 120 miles and at 50 mph or slower. Can also be used just for inflation. 10 3/4" L x 4" W x 6 3/4" H. (3 lbs.)
