BuraTAL HP 9650/HP is a new generation of sealing set from 6 sealing rings. The rings are constructed using non woven technology. The outer chamber rings are made from carbon fiber including stainless steel mesh reinforcement and impregnation. The next rings are made from aramid-PTFE non woven with stainless steel mesh reinforcement. Both central sealing rings are produced from aramid with PTFE impregnation. In particular applications a spindle bearing of carbon bushings might be required.
  • Excellent cross-sectional density
  • Good low friction properties
  • Greatly reduced creep
  • Lowest leakage rate
  • Ideal for control valve applications
