A pipe joint assembly comprises a plate having a bore which is at least partially threaded to receive a pipe, and a guide sleeve leading to the pipe and having a larger inner diameter than the diameter of the bore. One or both ends of the guide sleeve can include an annular lip protruding inwardly to center the pipe with the bore. In another embodiment of the invention, the guide sleeve does not include either annular lip, and instead is mounted off center with the bore such that a portion of the inner surface of the sleeve is flush with a portion of a surface defining the bore to center the pipe with the bore.
