The function of the Aston Seals SAW wiper ring is to prevent introduction of dust, dirt, foreign matter and heavily deposited ice and mud 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.
This type of wiper is designed to snap fit into its housing. To work properly it is important that its assembly is done with care.
The material used to produce this wiper is a special polyester resin that ensures excellent properties in case heavy applications, an increased wear-resistance and an extended service life.
