Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

Abstract: A water drainage device for a filter module is provided with a valve housing that has a valve bore and a valve body received at least in sections thereof in the valve bore. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to a valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and transferred from the open state into the closed state. The valve body, upon transfer of the water drainage device from the closed state into the open state, moves linearly along the longitudinal axis of the valve bore and away from the valve seat along or at a slant to a direction of gravity in downward direction.

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.

Abstract: An apparatus is disclosed. The apparatus includes a seal having an annular body including an upper surface and a lower surface. The annular body also includes an outer side surface and an inner side surface that join the upper surface to the lower surface. The inner side surface contributes to defining an endcap-engaging surface of the seal including: a first endcap surface engaging portion that is sized for engaging a portion of an upper surface of an endcap, a second endcap surface engaging portion that is sized for engaging an outer side surface of the endcap, and a third endcap surface engaging portion that is sized for engaging a lower surface of the endcap. The annular body includes an upper portion connected to a lower portion. The upper portion of the annular body of the seal is defined by a rounded seal portion. The lower portion of the annular body of the seal is defined by a flexible tang portion and a flexible leg portion. The flexible leg portion is connected to and extends away from the rounded seal portion. The flexible tang portion is connected to and extends away from the flexible leg portion. An endcap assembly is also disclosed. A filter assembly is also disclosed.
