Review on 🛠️ 4LIFETIMELINES Professional Brake Line Flare Kit for Single, Double (SAE) Flares & Bubble (ISO) Flares - Complete Set with 2 Flaring Bars, 12 Flaring Dies, Tubing Cutter, Tubing Reamer, & Storage Case by Kenyatta Mack

First of all, this article was not new to me because there was a big thumbprint on the instructions. Although I decided to try. Need two new 3/16 SAE fittings/double expanders for boat trailer brake line. So. It doesn't work on factory/steel lines, first try just flared, second try broke the die. I also bought a copper-nickel line there and it didn't work so well, or the bells bulged in between and were crooked with every attempt. Sent back definitely not worth 90€. I ordered a ready line from another source. Much luck
