You're right, they really aren't any different than the larger fittings and machining them is all the same process. The lathe I used had a collet setup so making these was really easy.

Thanks Doug. Not sure why I didn't find them in McMaster Carr.

Those you made look very nice. It doesn't look like too much trouble to do at the same time as the tube end fittings.

I ended up making my own on a lathe. The ones in the center of this pic:

Has anyone found a source for the compression tube PEM nuts, or another suitable 528 weld nut?
