Abstract
A sealing ring, for use in establishing a fluid-tight connection between the facing ends of tubular members which are to be braced axially with respect to one another, comprises a thin sheet-metal ring provided with a corrugation which defines an effective sealing ring thickness greatly in excess of the thickness of the sheet-metal. The sealing ring is provided with a non-metallic coating on both sides, the coating on at least one side being a layer which functions to achieve microsealing.
