A 37 GraphoFlon
Braided from Expanded Graphite Tape Reinforced with Inconel Matrix and special PTFE impregnation

Characteristics

  • No slip stick effect
  • High cross section density
  • High temperature resistant to minimize emissions
  • Non hardening, good reset capability
  • Coefficient of thermal expansion similar to steel
  • Easy to cut, install and disassemble
  • Low coefficient of friction minimizes the adjustment force in valves
  • Recommended as die formed rings
  • For valve applications rings should be approx. 25 - 30 % compressed at installation
