Abstract
A lipped sealing ring for a mechanical component that moves relatively to it. The lip is of a polymeric material, is flexible, and is forced subject to resilient compression against the component in the vicinity of a sealing gap. A helical shoulder extends longitudinally and at an acute angle to the axis of the component through at least one point along the circumference of the gap. The sealing gap is packed with wax at least in the vicinity of the helical shoulder.
