Abstract: Various embodiments of two-stage filter assemblies are provided. A filter element of the filter assembly includes a first endplate that is configured to facilitate assembly of the filter element into a filter housing assembly. The first endplate includes a flange that extends radially away from a media pack of the filter and into the channel formed between a lid and a housing of a filter housing assembly. A second endplate of the filter element is coupled to a media pack second end of the media pack. The filter element also includes a first seal member that is coupled to the second endplate. The first endplate and the filter housing assembly are structured to ensure that the filter element is sealingly engaged with the housing when (i) the flange is engaged with the lid and (ii) the lid is fully installed onto the housing.

Abstract: A fluid filtration system is provided. The system includes a filter head and a filter cartridge removably coupled to the filter head. The filter cartridge includes a shell housing defining a first housing end, a second housing end, and a housing sidewall extending between the first housing end and the second housing end. The filter cartridge further includes a filter element received within the shell housing and removably coupled to the shell housing. The filter element includes a media pack and an endplate. The media pack is configured to filter matter from a fluid flowing therethrough. The endplate is coupled to an end of the media pack. The endplate includes an expansible scaling member extending axially away from the endplate in a direction opposite to the media pack and having a compliant portion. The expansible sealing member is configured to expand in diameter when the expansible sealing member engages the shell housing.
