ABSTRACT:
A filter assembly and associated collection bowl for a dual contaminant collection zone arrangement use a self-sealing o-ring in combination with a threaded mating arrangement in order to withstand high pressure differentials. The filter assembly includes an end cap having a plurality of downwardly projecting ribs distinct from a threaded connector ring upon which the end cap rests. The end cap includes a number of contaminant channels between adjacent pairs of the ribs, the contaminant channels leading to corresponding contaminant outlets.
