S1A

The function of the Aston Seals S1A wiper ring is to prevent introduction of dust, dirt and foreign matter into the system. It is composed of:

  • A dynamic element with 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. The material used to produce this wiper assures exceptional low friction and high speed performance, high compatibility with nearly all media due to the chemical resistance which exceeds that of all other thermoplastics and elastomers
  • A standard size O-Ring with low permanent deformation as an energizing component on the static side which keeps the pressure of the wiper lip against the sliding surface and can compensate any defections of the rod.
  • Low static and dynamic friction
  • High speed allowed
  • No tendency of stick-slip
  • Space-saving construction and simple groove design
  • High compatibility with nearly all fluids (with the right choice of O-Ring material)
  • High temperature resistance
