Metal jacketed gaskets are a specialized type of gasket used for sealing applications in high-pressure and high-temperature environments. They consist of a metallic outer shell or jacket with a soft filler material, such as graphite, PTFE, or other materials, sandwiched between the layers. The metallic jacket provides mechanical strength and protection, while the filler material enhances sealing performance.

The outer metallic jacket of metal jacketed gaskets is typically made of materials like stainless steel, carbon steel, or other alloys chosen for their corrosion resistance and mechanical properties. The jacket can have various shapes, including flat, oval, or corrugated profiles, depending on the specific application requirements.

The filler material, located between the layers of the metallic jacket, serves to provide a tight seal against the flange faces and compensate for any surface irregularities. Common filler materials used in metal jacketed gaskets include graphite, PTFE, and various elastomers. The choice of filler material depends on factors such as temperature, pressure, and the media being sealed.

Metal jacketed gaskets are commonly used in industries such as oil and gas, petrochemical, chemical processing, power generation, and aerospace, where sealing performance is critical and operating conditions are demanding. They are particularly well-suited for applications involving high pressures, high temperatures, and corrosive fluids.

One of the key advantages of metal jacketed gaskets is their ability to withstand extreme operating conditions while maintaining a reliable seal. The metallic jacket provides excellent mechanical strength and protection against damage, while the filler material ensures effective sealing even under uneven flange surfaces or fluctuations in temperature and pressure.

However, proper installation and selection of the appropriate materials are essential to ensure optimal performance and prevent leaks. Careful attention to installation procedures, including torque specifications and surface preparation, is necessary to ensure the effective sealing of metal jacketed gaskets.
