Abstract: A tire pressure management system includes at least an axle enclosing a pressurized fluid, a hubcap supported by the axle and having an interior and an exterior, a rotary union axially aligned with the axle and mounted to the hubcap, the rotary union includes at least rotary union housing providing a central bore, a fluid conduit having upstream and downstream ends, a first bearing and a second bearing. Each of the bearings are in contact engagement with the fluid conduit via an inner race, and in pressing engagement with a bearing sleeve via an outer race, the bearing sleeve in pressing contact with the central bore; and a first and second seal, the first seal is disposed between the first bearing and the downstream end of the fluid conduit, and the second seal is disposed between the second bearing and the upstream end of the fluid conduit.
