A filter element, for use filtering liquids such as fuel, includes a first section of filter media, an optional layer of coalescer media, and a section of barrier media. The first section and optional coalescer filter media are held between opposite first and second end caps. The second end cap is integrated with the barrier filter media. The barrier media extends at least part way into an interior of the first section and can be conical in shape.

A filtration system includes a filter housing and a filter cartridge. The filter housing includes a base and a cover removably coupled to the base. The cover includes a retainer. The filter cartridge has a longitudinal axis and is movable between an installed position within the filter housing and an uninstalled position outside the filter housing. The filter cartridge includes a top endplate including at least one protrusion extending upwardly away from the top endplate. The protrusion includes a tab extending radially outward from the protrusion that is structured to interact with the retainer to removably couple the filter cartridge to the cover. The filter cartridge further includes a bottom endplate and a filter media extending axially between the top endplate and the bottom endplate.

A filter adaptor joins a canister filter to a hydraulic manifold block. The adaptor includes a hexagonal tool-receiving portion, an outflow passageway and one or more inflow passageways. The outlet flow passageway extends between opposed ends of the adaptor, and is used to direct filtered fluid from the filter to the manifold block. The inlet flow passageway(s) extend between the one end and a sealed region of the adaptor, and are used to direct fluid from the manifold block to the filter. The adaptor includes auxiliary ports formed in the tool-receiving portion that communicate with the inlet flow passageways and permit monitoring thereof.

A water purification filter element is provided. The water purification filter element may include a filter bottle, a filter material, an end cover, and a water self-stopping and passing structure.

A filter comprising a filter housing (10) and a replaceable filter element (12) arranged in the filter housing (10) and having annular upper and lower end members (12a, 12b) and an inner space, wherein the filter housing (10) comprises a housing pot (10a) having a fluid in-let (10e), a fluid outlet and an opening (10b) for inserting the filter element (12). The filter has a support tube (16) extending in the inner space of the filter element (12) and connected to a bottom of the filter housing (10) and a locking member (14), the locking member (14) being adapted to engage the support tube (16) and generate a holding or pushing or pulling force supported on the filter housing via the support tube (16) for holding or pushing or pulling the filter element (12) into or out of the housing bowl (10a).
