Abstract
Abstract An inflation valve for a tubeless tire according to the present disclosure includes a one-piece valve housing that is molded of a rigid plastic material. The housing has an internal passage threaded at one end to accommodate a valve core. The base of the housing has an annular groove defined in part, by a three part flange that permits the housing to be forced through a valve hole in the wheel rim. A rubber O-ring contained in the annular groove forms a seal between the valve housing and the wheel rim.
