HEAVY-DUTY PTFE SEALS

June 24, 2019

Kastas combines application engineering with modern designs and application specific materials, suitable for Heavy-Duty conditions.

Profiles

  • Double acting wiper K705
    • Low friction, free stick-slip
    • High sliding speed
  • Rod seal K704
    • Low friction, free stick-slip
    • High sliding speed
    • Minimum static and dynamic friction coefficient
  • Piston seal K755
    • Low friction, free stick-slip
    • High sliding speed
    • Simple groove design and low axial housing heights
    • No twisting in the housing

 

Materials

For sealing elements and wiper the standard material is PTFE-Bronze/NBR. For high frequency and short stroke applications, PTFE-Glass+MoS2 compound is preferred for sealing elements. For high temperature, FKM is used.
