  • Highly compressible PTFE outer layers seal under low bolt load-suitable for many non-metallic flanges
  • Compressible layers conform to surface irregularities, especially on warped, pitted or scratched flanges
  • Rigid PTFE core reduces cold flow and creep normally associated with conventional PTFE gaskets
  • Pure PTFE withstands a wide range of chemicals
  • Soft PTFE can be cut easily from larger sheets, reducing inventory costs and expensive downtime
  • Rigid PTFE core facilitates installation, especially on large diameter flanges and hard-to-reach areas
