The Encapsulated O-ring consists of a Teflon (FEP/PFA) plastic layer and a rubber core, which effectively combines the elasticity and sealing properties of the rubber with the chemical resistance of Teflon, and the surface is dense and uniform without seams.
FEP：Temperature resistant -30°C -220°C, can be used at 260°C for a short time
PFA：Temperature resistant -30°C -260°C, can be used at 300°C for a short time
Double-layer PTFE PTFE：-50°C - 260°C, special strong corrosion
