 Design introduction

屏幕截图 2025-10-15 210425

WDD combines the flexibility and responsiveness of O-Rings with the wear and friction characteristics of the PTFE materials in dynamic applications. The double-acting performance of the seal follows from the symmetrical cross section which allows the seal to respond to pressure in both directions.Initial contact pressure is provided by radial compression of the O-Ring



Advantages

  • Compact groove dimensions and simple installation

  • Low friction without stick-slip

  • Resistance against wear and extrusion

  • Piston seals available for all diameters from 5 to 999.9 mm

  • Fits also groove dimensions per ISO 6194 and AS 4716
