ABSTRACT:
A corrosion resistant tire valve assembly includes a valve body which is bonded at one end to an elastomeric base member that defines an outer sealing surface. A valve core assembly is threadedly mounted in the valve body, and this valve core assembly carries a seal member which is shaped to engage and seal against the outer sealing surface of the base member. In addition, the seal member extends up into an inner passageway defined by the valve core assembly. The cooperation between the seal member and the base member protects both the valve body and the valve core assembly from corrosion, as for example corrosion resulting from exposure to salt solutions commonly used to weight tires in agricultural and heavy construction applications.
