ABSTRACT:
A one-piece pipe coupling includes a cylinder with an axial joint and a sealing plate attached in spaced apart relation to the inner surface of the cylinder with a portion of the sealing plate extending beyond the axial joint for sealing the fluid pathways between a leak location and the outer surface of the coupling. A pair of arcuate gaskets extend around and are attached to the inner surface of the cylinder. The sealing plate carries a first sealing pad on the extending portion of its outer surface, which sealing pad includes circumferential guide channels for engaging the arcuate gaskets of the cylinder. The sealing plate also carries a second sealing pad on the other end of its outer surface, which sealing pad attaches the sealing plate in spaced apart relation to the inner surface of the cylinder. Further, the sealing plate carries circumferential sealing pad material on its inner surface to engage the arcuate gaskets attached to the inner surface of the cylinder, thereby forming a sealing connection around the pipe by the arcuate gaskets and the circumferential sealing pad material, and along both of the axial pads.
