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.

Abstract: A filter cartridge comprises a filter housing having a filter element disposed therewithin that comprises a filter media, and an end cap coupled to a top end of the filter media. The top end is positionable proximate to a filter head. A filter element outlet conduit extends from an inner rim of the end cap towards the filter head and is extendable into a filter head outlet. An end cap ledge extends radially outwards from an outer periphery of the end cap. A first sealing member is disposed at least partially on the end cap ledge and forms an axial seal with the filter head, and a second sealing member is disposed around the filter element outlet conduit on a radially outward surface thereof, and forms a radial seal with a radially inward surface of the filter head outlet conduit when the filter head is coupled to the filter cartridge.

Abstract: A filtration system includes a filter housing having a cavity and a base, a drain defined in the base, a channel defined in the base and in fluid communication with the drain, and a filter cartridge having a longitudinal axis and being movable between an installed position within the cavity of the filter housing and an uninstalled position outside the cavity of the filter housing. The channel defines an outer diameter. The filter cartridge includes a bottom endplate defining an outer diameter that is greater than the outer diameter of the channel so that, in the installed position, the bottom endplate covers the channel and prevents fluid flow from the cavity to the drain, and a filter media extending axially outwardly from the bottom endplate.

Abstract: A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.
