SIGRAFLEX® Economy flat gasket

Sigraflex Economy flat gaskets combine flexible graphite foils with one or two stainless steel foils (0.05 mm) for maximum stability. Thanks to oxidation and passive corrosion inhibitors, they guarantee outstanding resistance. Their chemical robustness and adaptability make them highly versatile. They remain soft and retain their compression and springback over long periods of time in the event of temperature fluctuations. Plus point: the bonded composite is PFAS-free.
