PTFE Gasket

PTFE Gasket-JinSeal

PTFE Gasket

Virgin | Expanded | Filled
Full | Raised Face
Round | Square
High Temperature


JinSeal PTFE -based Gasket Materials Are Able to Withstand Significantly More Aggressive Chemical Environments (including Highly Oxidizing Environments) Than Standard Non-asbestos Gasket Materials. However Their Temperature, Pressure and Mechanical Performance Are Inferior to Standard Non-asbestos Gasket Materials. Metal Inserted and Expanded Ptfe Are Able to Operate at Higher Pressures


  • Resistant to Strong Acids and Strong Alkalis, Resistant to Almost All Chemical Media, Except Molten Alkali Metals and Elemental Fluorine.

  • Outstanding Insulation Performance, Good Weather Resistance, and Weather Resistance.

  • the Coefficient of Friction is Low, and It is Not Easy to Bond, Easy to Install and Remove the Product is Clean and Can Be Used in Food, Medicine and Other Sealed Parts That Are Not Allowed to Be Contaminated

  • High Mechanical Strength, Good Turning Performance, and Easy Processing into Different Sealed Products.

  • the Coefficient of Linear Expansion is Low, and It is Easy to Produce Creep or Stress Relaxation when Cold Flow and High Temperature Occur After Compression. It is Not Suitable for High-temperature and High-pressure Parts.
