Filtration sealing system

A filter element removably receivable within a central compartment of a housing, comprising:

• filter media;
• and
• a seal member, the seal member comprising a complimentary non-planar sealing surface that matches (a) a first non-planar surface of a housing sealing surface of the housing and (b) a second non-planar surface of a cover sealing surface of a cover that is removably coupleable to the housing, each of the first non-planar surface and the second non-planar surface comprise a planar portion and non-planar portion, the non-planar portion comprises a triangular indentation defined axially in the seal member such that a vertex of the triangular indentation is located proximate to the housing sealing surface, the triangular indentation defined at an outer edge of the sealing member and having a width that is less than a width of the sealing member,
• wherein, when the filter element, the housing, and the cover are in a fully assembled state, the seal member is axially pinched between the housing and the cover by the housing sealing surface and the cover sealing surface to form a first seal between the seal member and the housing and a second seal between the seal member and the cover.

A method, comprising:

• providing a housing defining a central compartment and an outlet, the housing comprising a housing sealing surface having a first non-planar surface;
• providing a cover defining an inlet and comprising a cover sealing surface having a second non-planar surface;
• positioning a filter media of a filter element in the central compartment, the filter element also comprising a seal member, the seal member comprising a complimentary non-planar sealing surface that matches the first non-planar surface and the second non-planar surface, each of the first non-planar surface and the second non-planar surface comprise a planar portion and non-planar portion, the non-planar portion comprises a triangular indentation defined axially in the seal member such that a vertex of the triangular indentation is located proximate to the housing sealing surface, the triangular indentation defined at an outer edge of the sealing member and having a width that is less than a width of the sealing member;
• and
• coupling the cover to the housing such that the seal member is axially pinched between the housing and the cover by the housing sealing surface and the cover sealing surface so as to form a first seal between the seal member and the housing and a second seal between the seal member and the cover.
