Spiral wound gasket

A spiral wound gasket is a resilient, semi-metallic gasket made of a V-shaped metal strip and a soft filler material (like graphite or PTFE) wound together, providing excellent sealing for high-temperature, high-pressure, and corrosive industrial applications. It offers superior performance by combining the metal's strength and resilience with the filler's sealing ability, often including an outer guide ring to center it on flanges and an inner ring to prevent winding buckling into the pipe
