The port portion comprises inner port corrugations along an inner section of the port edge. A bottom of the ring gasket groove extends, along at least a major portion of the inner section, in a third plane, and, along at least a major portion of an outer section of the port edge, in a fourth plane. Plural of the inner port corrugations extend between and in the second plane and an intermediate plane between the first and second planes. The third and first planes extend on opposite sides of the intermediate plane.
