Detail GASKET, SPIRAL WND ( P/ N 907-596-039)
Spiral wound gaskets are to be constructed as alternate plies of preformed metal windings and plain fillers that are spirally wound when compressed between two flanges. A " v" and " w" shaped crown centered in the metal strip acts as a spring, giving gaskets greater resilience under varying conditions. Filler and strip 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.
