The valve parts assembled within the valve housing (20) include a self-sealing plug 40 and at least an upper retaining ring (44) holding the pressurized plug (40) in place within the valve chamber (32). The plug (40) can be apertured to receive an inflating needle and be oversized for diametrical compression into the valve chamber (32) to facilitate sealing.
