Introduction to PTFE Gaskets with Metal Mesh<\/strong><\/h2>\n

PTFE gaskets reinforced with metal mesh combine the chemical resistance of PTFE with the mechanical strength of stainless steel, delivering reliable sealing performance in harsh and hygienic environments. Widely used in chemical, pharmaceutical, food, and beverage industries, these gaskets are ideal for high-pressure, corrosive, and sanitary applications.<\/p>\n

Principaux avantages<\/strong><\/h2>\n

Unmatched Durability and Pressure Resistance<\/strong><\/h3>\n
    \n
  • \n

    Metal Mesh Core:<\/strong> 304 or 316L stainless steel (or custom alloys) embedded in PTFE provides exceptional mechanical strength and dimensional stability.<\/p>\n<\/li>\n

  • \n

    Creep Resistance:<\/strong> Prevents leakage caused by bolt relaxation or PTFE cold flow.<\/p>\n<\/li>\n

  • \n

    High Pressure Capability:<\/strong> Superior to pure PTFE gaskets, allowing multi-fold pressure handling.<\/p>\n<\/li>\n<\/ul>\n

    100% Corrosion Barrier<\/strong><\/h3>\n
      \n
    • \n

      Full PTFE Encapsulation:<\/strong> Metal mesh fully encased in PTFE, ensuring only PTFE contacts the medium.<\/p>\n<\/li>\n

    • \n

      R\u00e9sistance chimique :<\/strong> Withstands strong acids, bases, organic solvents, and harsh chemicals, providing full protection for chemical processes.<\/p>\n<\/li>\n<\/ul>\n

      Wide Operating Conditions<\/strong><\/h3>\n
        \n
      • \n

        Temperature Range:<\/strong> -200\u00b0C to +260\u00b0C, with short-term peaks up to +300\u00b0C.<\/p>\n<\/li>\n

      • \n

        Chemical Compatibility:<\/strong> Suitable for almost all corrosive chemicals and extreme environments.<\/p>\n<\/li>\n<\/ul>\n

        Hygienic, Safe, and Easy to Use<\/strong><\/h3>\n
          \n
        • \n

          Zero Contamination:<\/strong> Smooth, dense surface prevents adhesion, meets sanitary standards (FDA, EU 1935\/2004 optional).<\/p>\n<\/li>\n

        • \n

          Safe Installation:<\/strong> Low friction prevents twisting or damage; no fiber shedding, maintaining fluid purity.<\/p>\n<\/li>\n<\/ul>\n
