  • Patent number: 12257536
    Abstract: A filter element comprises one or more several tubular filter media element segments, which may be pleated filter media ring segments. One or more heat activated disks are used to connect each tubular filter media element segments together and/or to connect tubular filter media element segments with one or more end cap supports. The heat activated disks are solid in form for assembly with tubular filter media ring segment and then heat activated to bond with tubular filter media ring segments. Multiple end caps can be simultaneously bonded to one or more tubular filter media element segments if a filter stack assembly of component are heated together, such as in an oven. Filter media may also be simultaneously cured. Heat activated disks may be used as pleat stabilizers and/or for and/or as part of end caps.

  • Patent number: 11459986
    Abstract: The disclosed filter element is configured for use within a housing of a filter assembly. The filter element includes an obround ring of filter media extending between an upper and lower endcaps and defines a dirty wet fuel region. The upper endcap of the filter element defines an inlet for receiving the dirty wet fuel, which flows into the dirty wet fuel region and radially outward through the filter media. The upper endcap may include an insert to define a flow chamber to distribute fuel into the dirty wet fuel region. A clean wet fuel region is defined outside the filter element and within the housing. After flowing through the inlet and the filter media clean wet fuel fills the clean wet fuel region. A water separator is disposed external to the filter media and defines a clean dry fuel region in communication with an outlet defined by the upper endcap.
