Then you need a decent tool - like an Imperial Eastman or a Rigid 345 series for double flaring. Not cheap junk like Harbor Freight, but one that will last a lifetime. One caution, and depending on what you have, some OEM type calipers might
need a bubble flare, and that's a different can of worms.
