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.

Spin-on filter with external threads and methods

Liquid filter arrangements are described and shown. The arrangements generally include a filter member comprising a shell enclosing a filter cartridge. Unique features for interface between the enclosed filter cartridge and the shell are provided. Also provided are unique features for interaction between the cartridge and a filter head, in use.

Liquid filter arrangement; components; and, methods

A liquid filter arrangement is provided, as well as methods of assembly and use. Advantageous features, relating to a preferred filter cartridge and a preferred slide arrangement, are provided.

Liquid filter arrangements and methods

A liquid filter cartridge is provided. Preferred seal arrangements are provided, to provide for preferred axial load conditions, with respect to one or more of the end caps of the cartridge. Some cartridge configurations provided include no core structure or outer liner structure therein, to support axial load. Assemblies using the cartridge, and methods of assembly and use, are provided. The liquid filter cartridge can be a serviceable cartridge, or it can be retained permanently in a housing.

Filter cartridge for liquid filtration; assembly; and, methods

Filter cartridge for liquid filteration; assembly; and, methods

A top load liquid filter assembly includes a filter lockout mechanism to ensure that the filter base and cover are not connectable unless there is a proper filter cartridge installed therein. The filter system can also include an automatic drain mechanism and a cartridge retention mechanism. One example embodiment further includes an air bleed vent. A filter cartridge usable in the topload liquid filter assembly includes first and second protrusions and cover-gripper members. Methods of use, installing, servicing, and retaining can be practiced.
