ABSTRACT:
A coalescer or filter cartridge end cap having a disc-like base portion adapted to support filter media or coalescing media, and a central opening therein through which the liquid to be passed through the filter or coalescer flows. A counterbore section coaxial with the center line of the end cap forms a downwardly depending skirt having a lower edge adapted to receive a gasket. The skirt extends sufficiently to permit the cartridge equipped with the end caps of the present invention to be fitted over a wide variety of cartridge mounting stools, which normally include a short annular upstanding extension perpendicular to the cartridge sealing surface. Additionally, the inner diameter of the skirt is dimensioned to allow for sufficient clearance between the inner diameter of the skirt and the outer diameter of the stool extension, and is sufficiently long to afford clearance space between the upper end of the stool extension and the bottom surface of the base portion. Preferably, the inner diameter of the opening of the end cap is less than the outer diameter of the mounting stool extension.
