        Technical Data Sheet

        Benefits
        Tighter seal

        • 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

        Excellent chemical compatibility

        • Pure PTFE withstands a wide range of chemicals

        Easy to cut and install

        • 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

        Media
        Strong caustics, strong acids, hydrocarbons, chlorine and cryogenics. Conforms to FDA regulations.
        *For flat face flanges, a minimum compressive stress of 1,500psi is recommended on the contacted gasket area for 150psig liquid service. Consult with the flange manufacturer to confirm that adequate compressive stress is available.
