  • Asymmetrical, single acting rod seal, designed with interference on the OD which provides a good static fit in the groove.
  • Dynamic sealing lip shorter than static lip to avoid drag pressure.
  • Secondary lip for stabilizing at large seal heights and reducing the residual oil film.
  • Activated back-up ring prevents and reduces gap extrusion.
  • Excellent static and dynamic sealing performance.
  • Useable for long stroke lengths.
