Two internal passageways are formed within the interior of the check valve, each with an opening in the first portion and another opening in the second portion. The first and second portions each include a circular channel with flared walls into which one of the openings is formed. Each circular channel includes an O-ring which serves as a valve to control flow into the respective internal passageway.
