• a base coupled to the cover and defining an interface, the base being inboard of the cover and comprising a plurality of base ribs forming concentric rings extending from the base, wherein the plurality of base ribs extending from the base are offset from the plurality of cover ribs extending from the cover to form a labyrinth path between the cover and the base;
• a chamber between and defined by the cover and the base;
• an annular vent plug body extending in an inboard direction from the base where the base and the annular vent plug body defines a hollow cavity having a shield inboard of the base such that the shield generally traverses the hollow cavity;
