Contact

Spiral wound gaskets are a semi-metallic gasket consisting of a V-shaped thin metallic band plate and a non-metallic cushioning material. Capable of being used even under high temperatures and pressures and offering outstanding sealing performance, the gaskets are used in piping and equipment in a wide range of fields including oil refining, petrochemicals, power generation, and LNG terminals.
