Preferably, a rotary union assanblv includes at least a stationary tubular member defining an upstream end portion extending axially into an interior of an axle of a vehicle containing a source of pressurized air, and a downstream end portion upon which a housing is rotatably mounted. The housing of the preferred rotary union assembly is attachable to the exterior of a hub cap of the vehicle for rotation with the hub cap, and the housing preferably defines at least one air passagway extending therethrough that the tubular member communicates the source of the pressurized air with the passageway in the housing, and promotes passage of the pressurized air from the source of the pressurized air to a tire of the vehicle. Further, a rotary element is disposed within the housing of the preferred embodiment and provides a rotary element in abutting disposition with a stationary element.
