Abstract: A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

Abstract: 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.

Abstract: A fluid filter element for use in fuel filtration systems is disclosed. The filter element comprises, in an example embodiment, top and bottom end caps; filter media extending between the end caps and forming a central volume between the end caps; and an inner liner disposed in the central volume of the filter media between the end caps. A fluid passage is positioned in the inner liner extending between the end caps, the fluid passage being separate and independent of the flow through the filter media. A first seal is affixed to the bottom end cap; and a second seal with a central opening is affixed to the lower end of the inner liner. The inner lining may provide partial axial support to the filter media. An outer lining may also be included and provide partial axial support to the filter media.

Abstract: An endcap including a first plate member including a radial inner portion, a radial outer portion, and defining a longitudinal axis. The endcap also includes a flange disposed between the radial inner and outer portions of the first plate member and projecting axially along the longitudinal axis in a first direction. The endcap also includes a first seal member disposed adjacent the flange. The first seal includes a first portion thereof engaged with an axial facing surface of the first plate member and a second portion thereof engaged with a radially facing surface of the flange. The endcap further includes a second plate member disposed radially outward of the radial outer portion and a second seal member disposed adjacent the second plate member including at least a portion thereof axially spaced from the axially facing surface of the first plate member in a second direction along the longitudinal axis opposite the first direction.
