Serrated Gasket Aiflon serrated matallic gasket is the preferred gasket when improved performance at low seating stresses is required. It features excellent anti-blow-out properties linked with the reliably of a solid metal-to -metal seal combined with a soft sealing face to provide a tighter joint. It is particularly suitable for applications where high temperature, pressures and fluctuating conditions are encountered non-metal cover layers ensure that flanges are not damaged, even at extreme loads. This gasket is an ideal replacement for problem applications associated with jacketed gaskets, for heat exchangers, vessels and reactors and various flange connections.
