摘要:
A filter assembly includes a housing having an outer cavity and an inner cavity, and a gasket disposed within the housing. The gasket includes an inner surface, an outer surface, and a vent passage. The gasket forms a first seal with a central tube at the inner surface. The central tube extends into the inner cavity and includes an opening. A filter element is positioned within the housing and includes a filter media configured to filter a fluid and an endcap including an annular tab portion that forms a second seal with the outer surface of the gasket when the filter element is positioned in an operating position within the housing. The vent passage circumvents the first seal and the second seal, allowing air to flow from the inner cavity of the housing to the opening in the central tube.
