Title: Resilient insert for tire inflator

Abstract: A nozzle for use with a light, portable, miniaturized tire inflator. A resilient insert in the well of the nozzle enables it to be connected directly to the metal thread of a tire valve either by mating the insert with the screw thread or by pushing the insert onto the screw thread. The resilient nature of the insert prevents cross threading of the nozzle with the screw thread. During the inflation of the tire, the inflating gas exerts a force on the insert, thus causing it to compress. Such compression enables the insert to hold the screw thread and to provide a seal during the transference of the inflating gas without requiring any mechanical assistance to maintain proper contact with the valve.
