Abstract: A filter cartridge includes a shell, a connecting ring, an end cap, and an axially directed sealing member. The shell defines an inner cavity and an upper lip disposed along an upper edge of the inner cavity. The upper lip defines a channel. The connecting ring is positioned outside of the inner cavity and is engaged with the channel. The connecting ring includes a threaded region extending along a central axis of the shell. The end cap is engaged with the shell adjacent to the upper lip. The axially directed sealing member is positioned between the shell and the end cap and extends axially outward so as to form an axial seal with a filter head when the filter cartridge is installed on the filter head.

Abstract: A filter assembly includes a filter head and a filter cartridge. The filter head includes a filter head coupling surface, a filter head outlet, a filter head inner wall, and a filter head outer wall. The filter head coupling surface defines a filter head opening. The filter head outlet is configured to provide a fluid. The filter head inner wall extends around the filter head outlet. The filter head outer wall extends around the filter head inner wall. The filter head inner wall and the filter head outer wall collectively define a filter head channel. The filter cartridge includes a filter cartridge shell and a filter element. The filter cartridge shell has a filter cartridge coupling surface that is configured to be coupled to the filter head coupling surface. The filter cartridge shell defines a filter cartridge opening.

Abstract: A filter assembly comprises a housing defining an internal volume. An opening is defined at a bottom end of the housing. An adaptor is coupled to the bottom end of the housing. A filter element is disposed within the housing. The filter element comprises a filter media defining a central channel, and an endcap coupled to a filter media bottom end of the filter media proximate to the adaptor. A sealing member is disposed around the adaptor, the sealing member configured to form an axial seal between the endcap and the housing.
