BuraTAL T3 9650/T3 is a high grade universal sealing set for valve stems. This sealing set is completely made from high grade impregnated non-woven material. Two end rings made of carbon fibre non-woven material are impregnated with a special PTFE/graphite mixture. The middle rings consist of aramid non-woven material with a PTFE impregnation giving high cross-sectional leakage tightness.
  • Excellent resistance to gap extrusion
  • Very good recovery properties
  • Minimized cold-flow and creep behavior
  • Very good performance under temperature cycling
  • Unique combination of dimensional stability, cross sectional tightness and low friction capabilities
