Filter element

A method of making a filter element, comprising:

• providing a filter pack having oppositely facing first and second flow faces and having a flow path running through the first and second flow faces, the filter pack having an outer filter pack surface extending transversely between the first and second flow faces;
• arranging a seal support frame over one of the flow faces of the filter pack, the seal support frame including an annular extension having a tip in spaced relation from the second flow face, the seal support frame having an inner surface facing inwardly and an outer surface facing generally outwardly, the inner surface and the outer surface being on opposing sides of the tip;
• molding an annular seal member around the annular extension with a mold having an annular channel with the annular extension and urethane seal material received in the annular channel;
• and
• contacting the mold along the inner surface of the seal support frame at an annular mold contact in spaced relation to a terminating tip end of the annular extension, wherein only a single contact region at the annular mold contact exists between mold and the seal support during the molding of the annular seal member with the tip being elevated from a bottom of the annular channel with seal material extending around the tip along the inner surface and the outer surface.

• limiting rise of the seal material around the inner surface of the seal support frame with a projection projecting inward from extension.
