Abstract:
A leak repair device for rigid pipes comprising:(a) an elastomeric seal member having a central axis and a radial toroidal outer portion;(b) a semi-rigid flexible cover member having a peripheral skirt for holding said elastomeric seal member where said semi-rigid flexible cover member is so designed and constructed that upon radial compression of said semi-rigid flexible cover member, said semi-rigid flexible cover member will substantially conform to the curvature of said rigid pipe and where said elastomeric seal member is restrained from lateral displacement by said peripheral skirt during axial compression of said radial toroidal outer portion;(c) a clamp member associated with said semi-rigid flexible cover member for radially compressing said semi-rigid flexible cover member relative to said rigid pipe thereby axially compressing said radial toroidal outer portion against said rigid pipe to form a seal.
