The collar carries a wave spring and comprises followers which ascend a spiral ramp of the base for securing the disposable cartridge to the base in a positive locked position. The filter assembly also incorporates an efficient bleed orifice and a pair of axial spaced seal rings for implementing a fluid seal with the received disposable cartridge.
