Abstract
A leak repair device composed of an elastomeric seal having an outer toroidal portion radially of a central axis and a continuous membrane portion integral with and peripherally enclosed by the toroidal portion. The elastomeric seal is held by a semi-rigid flexible cover member which has a plurality of parallel slots extending across the surface of the cover member. As the cover member is compressed radially against a rigid pipe, the slots permit the cover member to bend to the contour of the pipe. The toroidal portion of the elastomeric seal is compressed against the pipe to seal the leak and the membrane portion encapsulates the leak region to further seal the escape of fluid through the leak repair device.
