As other reviews have mentioned these fittings do not fully tighten. I just tightened them as tight as I could with two fingers and had no problems. They look great and the recommended tube is the perfect size. I bought 3 packs and out of 12 fittings 1 had minor threading issues but I was able to fix the problem by opening and closing the fitting. To be honest I don't think I will ever buy anything else at this price. People who pay $10 a fitting are crazy. I've run them with no problems, no leaks, easy install, great price.
