Abstract
A caged filter cartridge assembly has a pair of coaxially spaced-apart end plates, and a number of tubular filter cartridges extending between said end plates. These end plates include seat recesses having a coaxially disposed retaining ring establishing an annular terminal lock edge. The filter cartridges include end caps at each opposed end thereof which are received within respective ones of said seat recesses. The end caps have at least one annular lock ring which is forcibly engaged with the terminal annular lock edge of the retaining ring so as to join the end cap, and thus said filter cartridge, to the end plates.
