ABSTRACT:
A filter assembly and associated collection bowl for a single or 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 may include an end cap having a plurality of downwardly projecting ribs distinct from a threaded connector ring upon which the end cap rests or the ribs may be integral with the connector ring and separate from the end cap. The lower end of the filter housing includes a number of contaminant channels between adjacent pairs of the ribs, the contaminant channels leading to corresponding contaminant outlets.
