splicing leaking brake line
Yes those work great but do not say whats it for or they might not sell it to you. I even use those hardware store ones 20 years ago and it work just fine but yeah get the better ones. I only had the car for a year till it went to the junk yard. They are easy to use, make a clean cut and put the nut on then slip the fitting on, should fit perfect, not loose. Thats what I would use, but I wasn't going to say it. Heck, it works fine why its a big no no ,not sure. Watch, someday the new car makers will start using it and it be ok then. Just like plastic fuel tanks and lines.
