Metal Gaskets

Metal gaskets offer distinct advantages over non-metallic types (such as rubber, elastomer, or fiber), making them ideal for demanding applications. Key features include:

• High Temperature Resistance: Constructed from metal alloys or composite metal-core structures, they maintain integrity under extreme heat.
• High-Pressure Capability: With superior load-bearing strength, metal gaskets are well-suited for high-pressure flanges, vessels, and piping systems.
• Durability & Longevity: They resist creep, aging, and degradation better than elastomers in harsh operating conditions.
• Chemical & Corrosion Resistance: Depending on the alloy, metal gaskets perform reliably with aggressive media, including acids, alkalis, and steam.
• Low Compression Set: Metals exhibit minimal permanent deformation, ensuring reliable sealing under cyclic or varying loads.
• Reduced Conformability: Their stiffness requires higher seating stress and closer attention to flange finish and bolt load compared to softer gaskets.

In summary, metal gaskets are the preferred solution for extreme conditions involving high temperature, high pressure, corrosive media, or cyclic loading.

Meridian manufactures a range of metal gaskets in various forms and materials, designed for high-temperature, high-pressure, and highly corrosive environments in equipment such as pressure vessels, valves, and cylinder heads.

• R-shaped oval and octagonal gaskets support maximum working pressures up to 10,000 PSI.
• RX and BX self-energizing gaskets can withstand pressures up to 15,000 PSI.
