Abstract
A metallic body is formed to have a clearance fit up into a reamed and spot faced tube extended through, and welded to a tubesheet. The form of the body provides a lip which functions to limit the distance the body can be inserted into the tube and supply filler material at the weld zone between the body and the tube.
