SA Wiper

SA

(Rod Wiper With External Lip)

The function of the SA wiper ring is to prevent introduction of dust, dirt and foreign matter into the system. 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. The SA rod wiper is produced in polyurethane which ensures excellent properties in case of dry run, an increased wear resistance and an extended service life due to good resistance against ozone and radiation caused by weather conditions.
