What Are Flexible Graphite Gaskets?
Flexible graphite gaskets are high-performance sealing components manufactured from expanded graphite. This chemically treated and thermally expanded form of natural graphite creates a highly compressible, conformable material that maintains tight seals in extreme temperature and pressure applications while resisting a wide range of chemicals.
How Flexible Graphite Gaskets Are Manufactured:
• Natural graphite flakes are intercalated with acid.
• Treated graphite is rapidly heated to temperatures exceeding 1,800°F (≈980°C).
• Graphite volume expands 200–300× into a worm-like structure.
• Expanded graphite is compressed into sheets, tape, or custom die-cut gaskets.
• No binders, fillers, or resins are required.
Key Performance Advantages:
• Excellent high-temperature capability.
• Broad chemical compatibility and inertness.
• High compressibility and conformability for tight sealing.
• Long-term sealing reliability and reduced fugitive emissions.
Flexible Graphite Sheet Gaskets Material for Extreme Conditions
This graphite gasket material is an excellent choice for high-temperature applications, such as steam services, heat exchangers, and high-pressure piping in industries like power generation, refining, and metallurgy. The material's flexibility allows it to conform to even the minutest surface irregularities, ensuring a tight seal. Additionally, its high thermal conductivity helps maintain effective heat transfer, which is crucial in applications involving temperature fluctuations and thermal cycling.
Flexible Graphite Gasket Benefits and Industry Uses
Durlon® Flexible Graphite sheet material delivers reliable sealing performance in demanding services where conventional gasket materials may fail. Its chemical resistance and thermal stability make it suitable for a wide range of industrial applications.
Typical Industry Uses:
• Chemical and petrochemical processing (pumps, valves, heat exchangers).
• Oil & gas production, refining, and transmission systems.
• Power generation, including boilers, turbines, and high-temperature piping.
• Pulp & paper, steel, and other heavy industrial operations.
• OEM equipment requires thin, high-performance sheet or cut gaskets.
