ABSTRACT:
An improved weldable vapor vent valve assembly comprising a non-weldable (heat-resistant) valve body and a weldable connector portion attached to an upper end of the valve body for welding onto the outer surface of a polymeric fuel tank. The weldable connector portion secures the valve body in place using vertical anti-leak ribs extending downwardly from the weldable connector and upwardly from the valve body which mate axially in an interlocking, sealing fit. The anti-leak ribs form a labyrinth-type seal that prevents liquid fuel and fuel vapor from leaking between the assembled portions of the vent valve assembly.
