This tube insert is designed to be used with a 1 1/4" heim joint or our Enduro joint in tubing with a 1 1/2" I.D.  This tube insert differs from our standard insert because it has a larger O.D. (2") at the area to be welded, it is the perfect insert to use if you are using 1/4" wall or thicker tubing.
