Abstract
A fluid filter assembly of a filtration system is described. The filter assembly described includes a cover member and a filter cartridge having at least one filter element and a plate member. The plate member includes a seal surface on one side facing the cover member, and a seal surface on another side facing away from the cover member. The seal surface facing the cover member is configured to seal with the cover member, and the seal surface facing away from the cover member configured to seal with another component of the filtration system. The assembly provides a structure that can retain a seal between sealing surfaces of the cover and the filter cartridge, at least while the fluid filter assembly is being serviced, so as to at least minimize fluid dripping and leakage.
