A filter assembly where the filter element is designed to connect directly to the spud of a vehicle fluid system, for example an engine lubrication system, a fuel system, or a hydraulic system. This provides a direct connection between the filtered fluid and the fluid system. The need for a seal between the top endplate and the nutplate, as well as the coil spring within the shell, which are found in conventional spin-on filter assemblies can be eliminated, which reduces inventory and the number of parts forming the filter assembly, and facilitates manufacturing of the filter assembly.

Filter element with threaded top endplate

A high-pressure filter assembly which includes a cover or nutplate secured to a housing via a sidewall portion of the housing deformed into a groove formed in the cover sidewall. The cover and housing are formed such that the cover can be properly seated upon the housing prior to seaming without special locators or beads formed in the container sidewall. A method and apparatus for forming the filter assembly are also disclosed.
