A male needleless connector (100) includes a body (110) having a male fitting (112) with a distal port (114), a valve (120) disposed within the body and having a first position wherein the valve seals the port and a second position wherein the valve does not seal the port, and a sliding seal disposed over a portion of the male fitting and having a first configuration wherein a first portion of the sliding seal is in sealing contact with the male fitting and a second configuration wherein the first portion is not in sealing contact with the male fitting. Moving the sliding seal to the second configuration opens the seal between the sliding seal and the male fitting and displaces the valve to the second position, thereby opening the seal between the valve and the port to provide a vent path (160) from the cavity between the sliding seal and the male fitting into the internal cavity (24) of a female counter connector (20).
