Since other manufacturers coding systems vary, this chart should not be used as a reference in identifying gaskets of unknown origin.
PTFE white Buna filler (TFWB) and PTFE encapsulated silicone (TES) contain all FDA approved materials.
PTFE accordion gaskets (TFACC) are recommended for use with viscous (thick) fluids only, maximum operating temperature 200°C.
Encapsulated gasket pressure ratings are reduced to 125PSI for ½" to 2½" at ambient temperature (21°C) when these gaskets are used.
PTFE encapsulated FKM (TEV) gaskets - maximum operating temperature 93°C.
PTFE encapsulated silicone gaskets (TES) gaskets - maximum operating temperature 107°C.
Maximum operating temperatures for specific chemicals may be lower. Contact Dixon™ for specific recommendations.
PTFE encapsulated FKM (TFVI) envelope gaskets - maximum operating temperature 180°C.
PTFE white Buna filler (TFWB) envelope gaskets - maximum operating temperature 80°C.
PTFE ethylene propylene filler (TFEP) envelope gaskets - maximum operating temperature 170°C.
