Bonded Seals are sealing discs used to seal screwed and flanged connections. They consist of a metallic flat ring and an elastic rubber seal bead. The carrier material is usually steel, stainless steel or aluminium. Various qualities of elastomer are used for the seal bead, depending on the application. Bonded Seals are also self-centring and available as shaped gaskets.
