This is achieved by a special wiper lip which produces a very effective cleaning action, prevents the development of scores, protects the guiding parts and extends the service life of the axial moving rod seals.
An external sealing lip on the outside diameter contacts the housing in order to prevent moisture entering the groove.
The internal ribs give stability and prevent twisting and sticking of the wiper in the groove.
