ABSTRACT:
A high pressure vapor vent valve for automotive fuel tanks is provided with bayonet-insertion, turn-to-lock locking structure mating with an opening in the fuel tank. An O-ring mounted on the valve body provides a fluid-tight radial compression seal between the valve body and the fuel tank wall to prevent leakage of fuel and fuel vapor therebetween. The O-ring radial compression seal is effected independently of the locking structure.
