Abstract: An air inflation device is a pass-thru vehicle tire inflation device. It ensures exact air pressure without the use of an air gauge. It works by attaching to a tire valve, and then to an existing air supply, such as those found at gas stations, and utilizing an internal pressure relief valve that is pre-set to exact PSI recommendations. This means that the inflation device will put only the amount of air needed in every tire without having to use a pressure gauge. Air moves through an internal air chamber constructed of plastic or rubber tubes that runs through the nozzle to the head that attaches to the valve of the tire. A plastic valve located on the back of the apparatus connects to any existing air supply. A pressure relief valve is integrated into the bottom of the nozzle that ensures that the exact PSI recommendations are maintained.
