Abstract
A non-vent axle hub cap features a dome forming a void for receiving a hub, a flange extending radially around the base of the dome, the flange having a plurality of securing apertures, and a grease zerk positioned in the top center of the dome. In some examples, the dome may feature a recess, with the zerk positioned within the recess and configured so that the top of the zerk is near, level with, or under the top of the dome. In use, when a user desires to add grease to the wheel bearings, a user may simply connect a grease gun to the zerk and pump in the desired amount of grease without the need of removing the hub cap.
