Hi everyone, I am retrofitting air con to a vehicle, and to make it look professional I want to make a hard line instead of all soft lines. If anyone knows, how does the machine work to make these flanged fittings? This subreddit seemed the most likely to know about pipe crimping.
I have attempted to make a tool to just press it from the end like a brake pipe crimper however this always resulted in the pipe distorting in Aluminium. I tried annealing and no dice.
I'm starting to think I need something inside like a small bead roller to pre bend it into a shape to then do the final press from the end.
Also if anyone knows what kind of grade of aluminium is used for these pipes and where to get it I would appreciate it.
TL;DR
I want to make a crimper to make these fittings, and what grade/type of aluminium pipe do I need?
Thanks in advance
