You are right, DS. That "upset" looks the same as beading. At $300 for a machine, I'll skip it unless I can find a local shop that has one and can put beading on a section of pipe for me.
Bill, thanks again for your much appreciated insight. I wasn't sure if the beading was absolutely necessary to keep the hose from slipping off of the nipple. I think I'll go with your suggestion of a plain ol' straight pipe.
I'm not sure if it is obvious by my tool question, but as far as my heater control valve saga goes, I've ordered a valve from Jim Carter this time. They supply a 5/8" x 3/4" elbow hose to adapt the HCV to my core. I'm going to cut off the beading on the 5/8" inlet and sweat on a transition and 3/4" pipe for the heater hose to attach to. Not elegant, but cheaper than the $90 rebuild.
Bill
