Mandrel tool CH-193 1/4'',5/16'',3/8'',1/2'',5/8''

A set of 5 steel pins for flaring the ends of copper pipes with diameters of 1/4", 5/16", 3/8", 1/2", 5/8". After properly heating the pipe ends, you can use the right pins and hammer to widen the pipe so that it is possible to insert an additional section into it to connect both by brazing. In this way, the need for an additional component in the form of a sleeve is eliminated and the amount of soldering is limited.
