ABSTRACT:
A filter element includes a cylindrical housing enclosing a ring-shaped filter media assembly. The media assembly includes inner and outer media rings, moveably supported relative to one another, to remove particulate matter and water from a fluid stream. The outer ring surrounds the inner ring and is sealed by a first seal to the housing. An end cap assembly at the upper end of the element includes an annular end cap piece attached to an upper end of the inner ring, a flat plate, and a threaded flange portion bounding the periphery of the plate. A second seal is provided between the upper end cap of the inner ring, and an upper end cap of the outer ring. The housing is secured to the media assembly by forming an open end of the housing around the flange portion.
