The first thing that you would need to consider is the attachments it came up with. Perfect sizes of adapters are an essential attachment that would need to play around with different sizes of flares. Try to look for 4mm to 10mm adapter sizes.

Added with heat-treated features would also an advantage you should look for. Also, consider something that can resist corrosion for a lifetime.


It is most neglected, but one of the essential features the best flare tool should have.
