PTFE Tetrafluoro-coated Asbestos Pad Gasket | Chemical-Resistant Sealing for Petrochemical Flange Connections


Product Overview
Our Tetrafluoro-coated Asbestos Pad Gasket (PTFE-coated Asbestos Gasket) is a high-performance sealing solution engineered for corrosive fluid handling in petrochemical, oil & gas, and industrial pipeline systems. Designed specifically for steel pipe flange connections and liquid pipeline valve sealing, this gasket combines the thermal resilience of asbestos with the superior chemical resistance of a Polytetrafluoroethylene (PTFE) coating. It is an ideal choice for sealing applications requiring reliability under aggressive media and variable pressure conditions.


Key Features & Benefits

  • Wide Temperature Range: Suitable for services from -100°C to +260°C, ensuring performance in cryogenic and moderate heat conditions.

  • High Pressure Resistance: Rated for operating pressures up to PN 4.0 MPa, making it suitable for a variety of process piping systems.

  • Excellent Chemical Resistance: Resists most chemical media, including acids, alkalis, and solvents—excluding elemental fluorine and chlorine trifluoride.

  • Anti-Stick & Non-Aging: PTFE coating prevents adhesion and ensures easy removal, even after prolonged use.

  • Long Service Life: Reinforced structure offers reliable sealing and reduced maintenance cycles in corrosive environments.


Compliant Standards
Manufactured in accordance with industry standards for dimensional consistency and material performance:

  • HG20607-97 | HG20628-97 | SH3402-96
