Engineered Gaskets >> Spiral Wound

SpiralWound Gasket are made with an alternating combination of formed metal wire and soft filler materials. They form an effective seal when compressed between two flanges. A V-shaped crown centered in the metal strip acts as a spring, giving gaskets greater resiliency under varying conditions. Filler and wire material can be changed to accommodate different chemical compatibility requirements. They can be used over the complete temperature range from cryogenic to approximately 550º degrees Centigrade. This type gasket can be used in all pressures from vacuum to the standard 2500 psi flange ratings. If the load available to compress a gasket is limited, gasket construction and dimensions can be altered to provide an effective seal. following four Main different spiral wound style is available.
