You'll want to do 37deg single flares with that. Make sure you deburr the ends before flaring to keep it from splitting. Also, It helps the seal to slightly burnish the flare inside if you can with the tool you have. Keep a steady pace on the flaring tool, don't stop and start if you can help it. Stainless work hardens pretty easily. I usually run 3/16 but 1/4 should work as long as your master is sized appropriately. also, make sure the flares seats straight and not cockeyed.
Oh, one more thing, Use steel 37deg AN fitting, NOT aluminum.
