Abstract: A bulkhead penetrator comprising a body having an interior and an exterior. An element having a first pressure is disposed within the body's interior in a first pressure region. An inner penetrator is configured to permit a transfer of the element from the body's interior past the physical boundary to the exterior of the body in a second pressure region having a second pressure, the inner penetrator having an interior surface exposed to the first pressure region and an exterior surface exposed to the second pressure region. An outer penetrator is configured to permit the transfer of the element from the interior of the body past the physical boundary to the exterior of the body in a third pressure region having a third pressure. An inner-outer connector connects the inner penetrator to the outer penetrator. Sealing mechanisms may prevent the transfer of the element from the first pressure region.
