Dynamic Slide Ring Double Acting:

Dynamic seal use where the O-ring not manage the pressure due to extrusion.
The seal can also be used where groove depth need to be minimize as much as possible.
The groove is an O-rings groove with 0, 1 or 2 back-up rings in following cross-section of the O-ring: 1.78, 2.62, 3.53, 5.33, 6.99 and 8.4 mm.

  • Compact groove dimensions and easy to installation
  • Low friction without stick-slip
  • Resistance against wear and extrusion
  • Piston seals available for all diameters from 5 to 1000 mm

Limitations on Use  
Operating pressure Up to 35 MPa (350 bar)
Velocity reciprocating to 15 m/s
Temperature -45 to +200 °C (depending on O-ring material)
