ABSTRACT:
A filter assembly including a filter housing defining an interior chamber with an open end, a filter disposed within the interior chamber, and a cover removably positioned over the open end to enclose the interior chamber. The filter housing defines an axially-facing sealing surface spaced from the open end. The filter includes a filter element and a flange element, with the flange element having a hook-shaped lip portion defining an axially-facing groove adapted to securely retain an O-ring seal therein. The cover includes an axially-extending sidewall portion and a laterally-extending flange portion, with the sidewall portion defining an outward taper adapted to retain an O-ring seal thereon. A clamp is used to bias the cover into sealing engagement with the open end of the filter housing. The cover in turn biases the flange element of the filter into sealing engagement with the axially-facing sealing surface of the filter housing.
