Abstract: A reduced area gasket has a sealing ring around the inside perimeter of the gasket. Remaining portions of the gasket are removed or compressed so that the bolt load is focused on the sealing area when the flange is tightened. In this way, the lower bolt loads mandated by plastic piping may be met, and the required sealing may be further obtained.
