To make this style flare, you need a very special style of tool. |
Hey,
I don't want to get into a technical argument because I'm no an expert myself, but DIN or ISO is a "bubble flare", I believe double is the term for SAE flare. I just spoke to my local Porsche mechanic about it, and he said they are technically not reusable because they have a crush zone for sealing, but 90% of the time you won't have any issues with it. He said when he does the work for customers he would have to re-flare the line, but he wouldn't worry about it on a personal car.
