Spiral wound gaskets are to be constructed as alternate plies of preformed metal windings (hoop) and plain fillers that are spirally wound when compressed betweentwo flanges. Filler and strip (hoop) materials can be changed to accommodate different chemical compatibility requirements. If the load available to compress a gasket is limited, gasket construction and dimensions can be altered to provide an effective seal.
