Braided from Expanded Graphite Tape, with Inconel Wire Matrix Reinforcement and a Special PTFE Film Coating


  • Avoids slip stick effect
  • High cross section density and sealability to minimize emissions
  • Wear and extrusion stability through structure reinforcement
  • Non-hardening, good reset capability, coefficient of thermal expansion like steel
  • Easy to assemble and disassemble
  • Low coefficient of friction minimises adjustment force in valvestem
  • Rings should be compressed to 25-30% of their height during installation
  • We recommend die formed rings
