ABSTRACT:
A fluid filter assembly (20) includes an axially extending tubular housing shell (24) having an integral closed end (26), a distally opposite integral open end (28), and a sidewall (30) extending integrally between the ends. An annular filter cartridge (32) is in the housing shell. An adapter plate (48) has a first set of threads (50) thread mounting the adapter plate to the machine (22) from which fluid is filtered, and a second set of threads (54) engaging the threads (56) of the open end of the housing shell in thread tightened engagement. The housing shell is a singular one-piece member of sufficient stock and thickness at the open end to be internally threaded and to structurally support direct threaded engagement with the adapter plate without an intermediate structural support member. The housing shell sidewall extending integrally between the ends is of sufficient stock and thickness to prevent torsional crimping thereof upon thread tightened engagement, including when the integral closed end of the housing shell is gripped and turned to turn the housing shell at the integral open end into direct threaded engagement with the adapter plate. In addition to simplified reduced part content, easy change of the filter cartridge is also enabled, wherein the adapter plate remains on the machine when the housing shell is removed.
