McElroy’s OneFit inserts make it possible to butt-fuse a range of pipe sizes on a single machine. The single insert design fits directly into the jaws of the machine without the need for additional master or nesting inserts. As a result, fewer items need to be stored, moved and installed. The inserts were successfully tested to the maximum fusion force on pipe with a DR 7 wall thickness to ensure their durability and strength. They are serrated to hold pipe firmly in place during fusion and are currently available in 36” and 48” jaw sizes.
