Piston seal KPOR30

Design Sketch
Installation Sketch

  • Symmetrical
  • Double-acting
  • O-ring as sealing and preloading element
  • Pressure compensation grooves on sealing surface
  • Tight fit on inner diameter
  • Tolerance of higher surface roughness in the groove base
  • Low friction even at low speed
  • High wear resistance
  • Suitable for dry running and deficient ulbrication
  • Suitable for high-temperature applications
  • Quick change of pressure and direction possible (lateral pressure relief notches)
  • No stick-slip effect
  • High extrusion reliability
Most commonly used in the following applications:
  • Sealing of pistons
  • For pressure load from both sides
  • Pressure compensation grooves allow fast pressure changes
  • Pressure compensation grooves prevent buildup of drag pressure and enable quick pressure changes
