Kind Code:
A3
Abstract:
Various embodiments relate to a filtration system. The filtration system includes a housing having a drain. A filter element is positioned within the housing. The filter element comprises a first endplate and a second endplate. Filter media is positioned between the first endplate and second endplate. A dual lip seal member is coupled to the second endplate. The dual lip seal member includes a first protrusion that extends radially outward around an outer surface of the dual lip seal member. A second protrusion extends radially outward around the outer surface of the dual lip seal member. The dual lip seal member is configured to prevent fluid to be filtered from exiting the housing through the drain when the filter element is in an installed position. The dual lip seal member permits residual fluid to exit the housing through the drain when the filter element is displaced from the installed position.
