A filter cartridge assembly having a unitary cartridge body with a protuberance extending therefrom. The protuberance is designed to sealably fit into a fixed connection disposed between the inlet and outlet portions of the fluid stream. The protuberance is provided with a first sealing member in the form of a feathered edge seal adapted to seal the cartridge inlet and outlet fluid streams respectively. Another seal spaced beneath the feathered seal in the form of an “O”ring serves as a frictional seal between the top of the cartridge body and the fixed connection. An annular fluid stream passage formed between the interior wall surface of the fixed connection and the protuberance, allows the cartridge body to be urged into the connection without regard to orientation of inlet or outlet fluid stream passages.

A filter cartridge assembly including: an elongated cylindrical chamber; filter media disposed therein; closure means affixed to the top portion of said chamber; fluid stream connecting means disposed in said fluid stream line having integrally formed inlet and outlet ports; said fluid stream connecting means being adapted to be cooperatively positioned with respect to said cylindrical chamber; cartridge connecting means integrally formed of said closure means for positioning said cylindrical chamber containing said filter media in cooperative working relationship with said fluid stream connecting means; tubular means disposed within said cylindrical chamber, being in communication with said cartridge connecting means for allowing the passage of fluid therethrough and into said outlet port in said fluid stream connecting means; passage means formed by said fluid connecting means for allowing the passage of fluid into said chamber interior; first sealing means affixed to said cartridge connecting means extending in a radial direction serving to seal the inlet and outlet fluid streams passing through said fluid stream connecting means; said first sealing means being defined by a feathered edge portion having associated therewith a flat undercut surface further defining a passage between said cartridge connecting means and said fluid stream connecting means to allow the passage of fluid into the inlet port of said cartridge connecting means, said undercut surface serving to provide additional dynamic force on said first sealing means to further enhance sealing at the contact surfaces between said first sealing means and said fluid stream connecting means; second sealing means disposed beneath said first sealing means serving to provide frictional sealing between said fluid stream connecting means and said closure means; central passage means formed in said closure means connected to said tubular portion and extending into and through said cartridge connecting means to thereby form an outlet passage means from the interior of said cylindrical chamber to and through the outlet port of said fluid stream connecting means; and fluid inlet passage means extending from an inlet passage in said cartridge connecting means to the chamber interior allowing the passage of inlet fluid through to the chamber interior.
