The present disclosure relates to a surgical access device for use during a surgical procedure that includes a housing, an access member extending distally from the housing, and a valve that is at least partially disposed within the housing. The access member is dimensioned for positioning within tissue, defines a longitudinal axis and a longitudinal opening, and has proximal and distal ends. The valve has a passage for the reception of a surgical object, and includes a proximal collar segment, a distal tapered segment that extends contiguously from the proximal collar segment, and a fluid resistive shelf. The fluid resistive shelf is generally defined at a juncture of the proximal collar segment and the distal tapered segment. The fluid resistive shelf and the distal tapered segment cooperate to substantially minimize the egress of fluids from the operative site about the valve.
