Abstract
A fluid filter has a filter element for filtering fluid. A nutplate having a threaded mounting portion is adapted to threadedly engage an externally threaded filter head. An inner seal retainer is positioned between the nutplate and the filtering element in order to define a hollow interior. The inner seal retainer has at least one stiff hollow web extending in a radial direction adapted to provide a space for transmitting fluid between the nutplate and the filter element. An inner radial seal is attached to the inner seal retainer for sealing the filter element with the filter head.
