Press-in filter spud that is free to spin

Abstract:

A filter element, filter head, a filter system and methods of assembling or mounting a filter element to a filter head are provided. The filter element and filter head have cooperating axially undulating sealing regions. The filter head has a spud that has a non-cylindrical region that extends through a non-circular opening in the filter element to communicate a central bore of the spud with a central cavity defined by filter media of the filter element. The method includes angularly aligning the undulating sealing regions by inserting the non-cylindrical region of the spud through the non-circular opening of the filter element.
