  • Symmetrical, single acting piston/rod seal, combined with pressure ring and support ring.
  • By adjusting the number of packings friction and leakage characteristics can be influenced.
  • Excellent static and dynamic sealing performance.
  • Excellent performance in high pressure conditions.
  • Useable for short and long stroke lengths.
  • High wear resistance.


Reciprocating pistons/rods in hydraulic cylinders, plungers etc.

Used in heavy duty applications (presses) with return stroke by equipment weight. Max. pressure 500 bar, max. speed 0.5 m/s.


Installation normally in open housings.

At closed housings the parts need to be split. In this case the seal must be done  slightly larger (approx. 1% in diameter)
