Abstract

A sealing element (60) for an annular filter element (100) of an oil separator (200) of a crankcase ventilation system, wherein the annular filter element (100) is configured to separate oil from fluid. The sealing element (60) fulfills more than one sealing function and yet is easy to use and replace. The sealing element (60) having at least one radially sealing region (64) that is configured to act in the direction of the radius (120) of the annular filter element (100), and at least one axially sealing region (66) that is configured to act in the direction of the longitudinal axis (110) of the annular filter element (100).
