I just bought a Masterkool hydraulic flaring tool for work. It is not cheap but OMG is it incredible. Perfect double flares in less than two minutes. The ends I’ve made look better than they come with from the parts store. View attachment 1716055199
I too have this tool, I've plumbed 6 cars with it, brakes, fuel,trans, etc,
not one bad flare, (even when I was just learning how to use it)
simple, quick, eazy,
but ,there are always some who just can't work it,
