The function of external wiper ring Aston Seals SAA is to prevent introduction of dust, dirt and foreign matter into the single-acting cylinder which has an opening to the atmosphere.
This is achieved by a special external wiper lip which produces a very effective cleaning action on the internal cylinder surface, prevents the development of scores, protects the guiding parts and extends the service life of the axial moving piston seals.
The material used to produce this wiper is a polyurethane compound that ensures excellent properties in case of dry run, an increased wear-resistance and an extended service life.

  • Excellent wear-resistance
  • Extended service life
  • No close tolerances are necessary
  • Low cost solution
  • Space-saving construction
  • Easy installation without expensive auxiliaries
