Abstract
In a filter element, such as an air filter element used for filtering engine air or cabin air in vehicles, a pleated filter media is disposed within a plastic frame and retained therein by the same material which is used to form a gasket for sealing with a housing in which the filter element is mounted. The gasket is formed of polyurethane foam or any other flexible sealing material such as plastisol or silicone and is cast molded around the outer periphery of the frame over a plurality of interlocking tabs. The seal is therefore mechanically locked to the frame as well as being adhered to the frame.
