Abstract: A valve stem and cap apparatus includes a valve stem having a base for attachment to a rim and a tubular sleeve extending upwardly from the base, the sleeve defining an open end. A stem valve is positioned in the sleeve for regulating air flow therethrough. A pair of resilient flanges are positioned on an outer surface of the sleeve adjacent the open end. The apparatus includes a cap having a cylindrical configuration with an open end for selectively covering the open end of the sleeve. The cap defines a pair of oppositely disposed apertures for releasably engaging respective resilient flanges in a snap-fit relationship when the cap is positioned to cover the open end of the sleeve and appropriately rotated.
