ABSTRACT:
A device is disclosed which is adapted to be inserted in the threaded end of the sleeve of a pipe coupling to permit connection of piping thereto having either a convex-shaped end or a straight-tubular end by means of a correspondingly threaded nut which is capable of exerting an axially compressive force on the device. The device has a through bore, a portion of which is a socket substantially concave in shape for receiving the convex-shaped pipe end and a portion which is tubular in shape for receiving the straight tubular pipe end.
