Abstract: A valve for controlling fluid flow through a flow passage. The valve includes a tubular valve body defining a longitudinal axis and having an interior surface and an exterior surface. The valve body defines first and second valve ends and a tip portion is supported on the valve body and located at the second valve end. A cap member is supported on the valve body and includes a closed end formed by an end wall having an aperture for receiving the tip portion. The aperture includes a lip portion surrounded a groove on an interior of the cap member to facilitate a pressure seal between the aperture and the tip portion.
