The best flare tool I’ve actually used is the Eastwood flare tool in this video.
Perfect flares EVERY TIME unless I am careless (in too much of a hurry). I bought a new flare tool that is more portable and have not used it yet. I made a few test flares on some steel line and it seems to be fine. The advantage of the new MASTERCOOL hydraulic tool is that flares can be made “on the vehicle” rather than needing to take the tubing to the workbench. Plus it has more dies to make all sorts of flares that the Eastwood tool doesn’t have in the kit.
