PTFE gaskets are precision-engineered sealing components made from polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene. They are highly valued in industrial sealing applications due to their exceptional chemical inertness, thermal stability, and low surface energy, making them compatible with a broad range of aggressive media and operating conditions.https://www.magpievalves.com/ptfe-gasket.html
