PTFE gaskets are made of synthetic fluoropolymer of tetrafluoroethylene consisting completely of carbon and fluorine. It is innately hydrophobic (repelling water and water-containing substances) and has one of the lowest coefficients of friction against any solid.

PTFE Gaskets are one of those widely-used components across industries. PTFE or Polytetrafluoroethylene that is commonly known as TEFLON is used as a gasketing material by PTFE gasket manufacturers because of its physical and chemical properties.
