ABSTRACT:
A self-sealing pressure valve assembly which eliminates O-rings by providing a tapered annular projection on one side of a wall closely surrounding an opening through which the valve is installed. A complementary engaging projection is provided on a locking member of the valve assembly. In addition, the wall opening and the valve body are tapered on the side opposite the projections. Thus, the projections provide a seal on one side of the wall and the tapers provide a seal on the other side of the wall when the locking member fully engages the valve body, as by threads.
