See full text

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.
