Butt Fusion Inserts
McElroy fusion machines will fuse a range of pipe sizes. To be able to fuse multiple pipe sizes you will need to purchase inserts for the pipe sizes you want to fuse. Inserts are made for one size pipe only and not all inserts fit directly in the jaws. Some inserts nest inside other inserts, called master inserts. These master inserts will need to be purchased also.
Set = 4 Inserts, screws, wrench
