A dual sealing system (20) is provided for use with a probe (21) to allow access to an interior space (34) from an exterior environment (32). The system (20) includes a housing (22) defining a port (24) extending along a longitudinal axis (26) between an exterior end (28) of the housing and an interior end (30) of the housing to establish communication between an exterior environment (32) and an interior space (34); a first flexible, resilient penetratable member (40) extending across the port at a first location along the axis, the first penetratable member configured to create a seal around the probe with the probe inserted therethrough; and a second flexible, penetratable member (42) extending across the port at a second location along the axis spaced toward the interior end from the first location, the second penetratable member configured to create a seal after having been penetrated by the probe and the probe has been removed from the second penetratable member.
