Special high performance packing of aramid yarns corners and expanded PTFE graphite fibre yarns at the running surface

  • Ideal packing for services where chemical resistance, high strength and sliding properties are essential
  • The special aramid fibres at the corners enhance pressure and extrusion resistance of the packing even at higher temperatures
  • Excellent resistance to abrasive media, low friction packing
  • Can be used in all aggregates with a large clearance/gap

Available in rope and ring form
