Abstract
This tire valve comprises a brass stem having an elongate insulating sleeve over it, the sleeve being circumposed by a flanged threaded metal body which is provided with a gasket and a clamping nut to clamp the valve to the wheel. Electrically insulated from each other are a pair of contact rings held respectively against the clamping nut on the body and a second final nut contacting the stem, the rings having take-off leads. A molded rubber shroud protects the rings and holds them and an insulating spacer in proper relation.
