I'm looking for the dimensions of the female end so I can make a swaging tool to duplicate that geometry.
Also got into the aluminum brazing just for fun.
For starters I'm using the AL822 rods from Lucas Milhaupt...822°F melting point with MAP gas....it flows into the joint almost as good as silver brazing.
I'm anxious to see how it performs. I'll be pumping it down in a few days.

nothing short of amazing work you do.... I am going to look into that rod you mentioned and give it a try. The Uniweld brand Aluma-Braze looks and flowed awesome except 2 of 3 joints I got leaks when nitrogen testing the fittings... not sure whats happening.
did you make a forming die for the male o-ring end in that picture?
