PS20

Function
Piston seals are designed to seal the pressurized hydraulic fluid against the atmosphere
or between two pressurized spaces.
Features
  • Asymmetrical, double acting compact piston seal, designed with interference on
the ID which provides a good static fit in the groove.
  • Excellent static and dynamic sealing performance.
  • Excellent performance in low pressure conditions.
  • Negligible tendency to “stick-slip” effect.
  • High break-away load after long standstills.
  • Activated back-up rings reduce gap extrusion and prevent twisting of the seal in
the groove.
Application
Reciprocating pistons in hydraulic cylinders, plungers.
Static and dynamic seals in hydraulic systems, replacement for O-Rings (no twisting or
pumping).
Max. pressure 700 bar, max. speed 0.5 m/s
Installation
Snap-in installation.
