  • 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.
  • Excellent static and dynamic sealing performance.
  • Useable for long stroke lengths.
  • Negligible tendency to “stick-slip” effect above a speed of 0.15 m/s.
  • For lower speeds the dynamic lip should be redesigned (shorter, stiffer).
  • Activated back-up rings prevent and reduce gap extrusion.


Reciprocation rods in hydraulic cylinders, plungers.

Universal rod seal for larger extrusion gaps and higher load impacts.

Max. pressure 700 bar, max. speed 0.5 m/s, depending on material selection.


Snap-in installation.
