Times three on ni-copp line. Flares really nice. The cheap flaring tools are hit and miss on how well they make flares. When you cut the lines don't crush it with tubing cutter and deburr the inside of the tube. I use 3/16" every where.
If you don't want to buy a flaring tool form the lines as needed and the take them down to a repair shop with a good flaring tool. That's what I did before I bought good flaring tool.
