ABSTRACT:
A metal, U-shaped, annular cap is placed over one end of a cylindrical body of filter material. The metal end cap is retained on the body of filter material by a layer of plastisol and has adhered to the outside surface thereof an annular gasket made of either polyurethane or a closed or opened cell foam. The gasket presents an axially extending sealing surface for effecting a radial seal with a sealing flange in a filter housing. In accordance with another embodiment of the invention, a second annular gasket is provided which is adhered to the surface of the U-shaped end cap and extends axially therefrom. The second annular gasket has a radial surface for effecting an axial seal with a filter housing configured for axial sealing with filter elements disposed therewithin.
