Filter elements and assemblies

Abstract

A filter cartridge can include a media pack including media extending between a first end and a second end along a longitudinal axis; an end cap secured to the media and including: a seal member presenting a radially inward or outward facing seal surface, the seal member being formed from a first material; and a support structure including a base part and a plurality of spaced apart, radially flexible extensions, the support structure being formed from a second material harder and/or stiffer than the first material. At least a portion of the base part is covered by and/or embedded within the first material, and the plurality of flexible extensions includes an exposed portion that is uncovered by and/or embedded within the first material and defines an axial end of the filter cartridge and is coincident with a radial innermost portion of the end cap. The seal surface and the exposed portion of the flexible extensions are axially aligned such that a plane orthogonal to the longitudinal axis can pass through the seal member and through the exposed portion of the plurality of flexible extensions.
