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. |
