Abstract: A repair apparatus and method is utilized for repairing leaks, ruptures or weaknesses in ell pipe fittings. An arcuate reinforcement structure conforms to the radius of curvature of the convex side of the fitting and a second arcuate reinforcement structure conforms to the curvature of the concave side of the fitting. One or both of the reinforcement structures urges a sealing member against the fitting, with at least one of the sealing members sealing over the leak, rupture, or weakness. The reinforcement structures may have integral bands which may attach to encircle the fitting.

Abstract: An adapter encircles and locks around nut members of pipe unions or nuts made up on fasteners, and engages the nut member in locking contact. The adapter has strike surfaces which allow the nut member to be tightened or loosened by a hammering means, such as a hammer, mallet or sledge hammer. Thus, in the case of a pipe union, the device temporarily converts a nut union to a hammer union. The apparatus is configured to facilitate attachment of the device in tight situations, such as attaching the device to the nut member of a pipe union on a piping manifold having closely spaced parallel pipelines.
