Material Notes:
Microcellular PTFE gasket with rigid PTFE coreHighly compressible PTFE outer layers seal under low bolt load- suitable for many non-metallic flangesCompressible layers conform to surface irregularities, especially on warped, pitted or scratched flangesRigid PTFE core reduces cold flow and creep normally associated with conventional PTFE gasketsMedia: Strong caustics, strong acids, hydrocarbons, chlorine and cryogenics.Conforms to FDA regulations.Information provided by Garlock Rubber Technologies
