That's the big brother of the one you need. They also sell a wrench for bending tight radius.
Do some sample bends to learn where the pipe doesn't bend. I'll try to take a picture how to line up the tool to make a perfect match. Since the radius will be different..

I can't tell if that has 3/16 size but some of the bends are tighter radius than possible with the tubing bender.
I just picked up some flare crow foot sockets ironically SAE since I need 11mm and 16mm and the metric size had neither.
