Insulation gaskets are specialized sealing components used to prevent the transfer of heat, electricity, or fluids between two connected surfaces. Made from materials like silicone, EPDM, and FVMQ, they offer excellent thermal resistance, electrical insulation, and sealing performance. Commonly used in automotive, chemical, and power systems, these gaskets are available in customizable shapes, sizes, and hardness levels to meet diverse industrial requirements.Insulation gaskets are specialized sealing components used to prevent the transfer of heat, electricity, or fluids between two connected surfaces.
