  • Asymmetrical
  • Sharp, cut sealing edge
  • Shortened outer lip
  • Support ring
  • Pressure compensation grooves on sealing surface
  • Good static and dynamic sealing effect
  • High extrusion reliability
Most commonly used in the following applications:
  • Sealing of pistons
  • Use with one-sided pressure load
  • Use with pressure load on one side, in case of pressure load on both sides assembly of two sealing sets in back-to-back arrangement
  • Support ring as gap closure element prevents gap extrusion
  • Pressure compensation grooves prevent buildup of drag pressure and enable quick pressure changes
