A press plug for use in an inflation system for supplying air to the rotating tires on a vehicle. The press plug provides the function
of sealing pressure in an axle and providing support by rotary air connection by engaging the inside of the axle and being held in
place by an interference fit. The press plug includes a tapered flange for providing both a seal and retaining feature for holding
the press plug in position.
