The Spiral Wound Gasket with Inner & Outer Rings is a premium sealing solution designed for high-pressure and high-temperature applications, ensuring maximum leak prevention and long-lasting performance.
It is constructed from a V-shaped metal winding, typically stainless steel, combined with a soft filler material such as graphite or PTFE for excellent sealing efficiency. The inner ring provides additional protection to the sealing element by preventing inward buckling and protecting against erosion, while the outer ring acts as a compression limiter and aids in correct gasket centering during installation.
This design is ideal for flange connections in pipelines, valves, pumps, and heat exchangers across industries such as oil & gas, petrochemical, power generation, and marine. It meets international standards like ASME B16.20 and is available in a range of materials to suit different media and operating conditions.
