A 99 Spezialgraph
Braided of Flexible Expanded Graphite Tape with High Temperature Inconel Mesh Reinforcement

Characteristics

  • Universal plant wide use in static applications
  • Extrusion stability through ultrafine 10 myh Inconel mesh reinforcement on each strand
  • Non hardening, good reset capability, coefficient of thermal expansion corresponds to the coefficient of steel
  • High temperature and pressure resistance
  • Easy to cut, assemble and disassemble
  • Low coefficient of friction minimizes the adjustment force in valves
  • For valve applications rings should be approx. 25 - 30 % compressed at installation
  • A 99 can be used as bullrings for style A 44 I, P60 and ARF
  • Die formed rings are recommended
  • Contains effective passive corrosion inhibitor
