摘要：
A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.
