AD

The rod seal type Aston Seals AD assures a good reaction against shock pressure peaks and low friction in the low pressure range.
The asymmetric lips are designed to differentiate the behaviour of the lips on the static and dynamic surfaces: the static lip is flexible and more sensitive to pressure fluctuations; the dynamic lip is shorter and stronger to concentrate load against the dynamic surface.
Wear and dry run are largely prevented by additional lubricant retained within the gap created by the secondary lip.
The material used to produce this seal is a polyurethane compound that ensures excellent properties on wear-resistance, extended service life and resistance against extrusion.

  • Extended service life
  • High resistance against extrusion
  • Excellent wear-resistance
  • Good temperature resistance
  • Insensitive to structural deflections
  • Easy installation without expensive auxiliaries
