Buraflex HT 2000/HT For a larger view, please mouseover the image.
EagleBurgmann Buraflex HT 2000/HT is made from diagonally braided permanently elastic graphite foil with a high performance lubricant. Therefore it is the pump packing for high temperatures and very high sliding speeds. The combination of graphite body yarn and Nomex yarn corners provide high long-term strength and resistance to corner extrusion.
  • Outstanding cross sectional density
  • High thermal conductivity
  • Excellent abrasion resistance
  • Very good anti-extrusion properties
  • Gentle on shaft surfaces
  • No hardening
