Robust and versatile carbon fiber packing.

Type 98 is made of high-purity (95% + carbon) premium grade carbon fiber. Before weaving with a high-temperature non-petroleum-based lubricant, a single fiber was coated with a stone mill dispersant at one end and dried at one end.

Features / Benefits
  • Low coefficient of friction to extend equipment life and reduce shaft wear
  • High thermal conductivity means lower process operating temperatures and longer packing life
  • Excellent chemical resistance
  • Obtained low chloride certification
extra information:
  • When used as an end ring material with the die-cast GRAPH-LOCK® centering ring, the pressure limit for Model 98 has not been determined.
  • We can request certification for less than 200 ppm of dissolved chloride.
