Abstract
A cartridge filter has a unitary upper fitting and a separate gasket which permits a single base filter to be used with a wide range of tube sheet openings, simply by selecting the appropriate gasket. In one embodiment, the gasket is bonded to the unitary upper fitting. In another embodiment, the tubular side wall of the unitary upper fitting defines an annular step, and the gasket defines a bottom edge, at least a portion of which rests on the step.
