Introduction to Metal Jacketed Gasket Dimensions

Metal jacketed gaskets are critical sealing components that combine the resilience of soft filler materials with the durability of metallic outer shells. These semi-metallic gaskets are engineered to withstand extreme temperatures, high pressures, and corrosive environments in industrial applications.

Proper dimensional specifications are essential for effective sealing performance. Metal jacketed gaskets must conform to precise tolerances as outlined in ASME B16.20 standards, which govern materials, dimensions, and markings for metallic gaskets used with pipe flanges.

Available in both single and double jacket configurations, these gaskets serve diverse applications including heat exchangers, pressure vessels, valve bonnets, and high-temperature piping systems. The jacket material—typically stainless steel, Inconel, or other specialized alloys—protects the compressible core while maintaining structural integrity under demanding service conditions.

Understanding the correct dimensional parameters, including inside diameter, outside diameter, thickness tolerances, and pressure class requirements, is crucial for engineers and procurement professionals. Our comprehensive dimension guides below provide detailed specifications for various gasket styles, helping you select the optimal sealing solution for your specific application requirements.
