Gaskets for sealing two mating surfaces have an inner ring positioned between two inner sealing deformable layers and an outer ring positioned exterior and concentric to the inner ring, the outer ring positioned between two outer sealing deformable layers. The two inner sealing deformable layers are configured to compress a greater amount than the two outer sealing deformable layers when a compressive force is applied. In a compressed configuration, the two inner sealing deformable layers fill in the crevices of the mating surfaces of a corroded flange connection thereby avoiding immediate maintenance for the damaged flanges. The inner and outer rings have grooves and ridges on upper and lower surfaces to retain and receive portions of the inner and outer sealing deformable layers in a sealed flange connection.

Sealing device for flanges

A gasket ( ) comprises a sealing member which forms a closed loop extending around a hole. The sealing member is formed from resilient metal and has a transverse cross section which is generally X-shaped and comprises two arms ( ) which project inwardly of the hole, and two arms ( ) which project outwardly of the hole. The inwardly projecting arms form a first seal around said hole, and the outwardly projecting arms form a second seal around said hole. Each arm extends from a junction ( ) with the remainder of the gasket to a tip ( ) of the arm which engages one of the bodies. Each arm has its greatest thickness at said junction ( ) and its smallest thickness at a point adjacent to or at said tip ( ), the arm continuously reducing in thickness between said junction and said point. The gasket can yield from the tips of the arms inwardly as the pressure on the gasket increases.
