A filter cartridge for insertion into a filter head having fluid inlet and outlet ports and adapted to be permanently mounted in a fluid conduit comprising: (a) a pressure vessel closed at one end and adapted to have a filter element disposed therein; (b) a closure member in sealed relationship with the open end of said pressure vessel, said closure member being formed with inlet and outlet ports therein for communicating with inlet and outlet ports in a filter head with which the filter cartridge is adapted to be associated, said closure member also being formed with a pair of unequal diameter concentrically disposed axially projecting tubular portions which define inlet and outlet ports to and from the pressure vessel, one of said tubular portions extending axially beyond the other; (c) a first pair of laterally extending oppositely disposed lug members formed on the outer surface of said pressure vessel; (d) a second pair of laterally extending oppositely disposed lug members formed on the outer surface of the tubular portion having the larger diameter; and (e) means formed on said second pair of lug members for coacting with a portion of a filter head with which the filter cartridge is adapted to be associated, said means formed on said second pair of lug members being adapted to function in coaction with a filter head to restrict potential axial movement during operation and under pressure of said closure member relative to said pressure vessel.
