ABSTRACT:
A sealing plate which is positioned under annular O-rings or built-in coupling gaskets. The sealing plate carries gasket material on its inner surface to complete an annular seal around the pipeline on either side of a leak location, and on its outer surface to prevent fluid from reaching the axial joint of the coupling between the annular seal. Once one positions the sealing plate properly, the annular gasket material does not become misaligned. Furthermore, the sealing plate can be used interchangeably with discrete O-rings and a coupling, or with a coupling having built-in arcuate gasket sections.
