A seal module for sealing between a first door and a second door of opposing-hinged doors is moveable between an sealing position for sealing between the first door and the second door, and a withdrawn position longitudinally spaced from one of the first door and the second door to allow for independent pivotable movement of either the first door or the second door. A linkage system including a first swing arm and a second swing arm rotatably interconnects the seal module to the second door, and moves the seal module between the sealing position and the withdrawn position along an arcuate path that is disposed along a plane substantially perpendicular to an outer surface of the opposing-hinged doors.
