Review on 📏 Accurate Brake Line Fitting Size Gauge for 4LIFETIMELINES Products by Major Lindsay

I bought other "4 Lifetime Lines" products and was happy with them. made but I believe mine was assembled at the end or beginning of the work week. I have (2) caliber 7/16-20, I'm missing 3/8-24 (the one I use the most). Ok, mistakes happen. So I tried different (more than one) 1/8 NPT, and these gauges have 1/4 NPT connections. No bueno. You might get 1 thread and it sticks, the NPT thread size is bad/useless. I've tried every other fit, 7/16-20, 7/16-24, 1/2-20, 9/16-18, 9/16-20, 5/8-18 and they all cut correctly. No problem. So if you're only interested in standard brake line fit sizes, you should be fine. Don't rely on 1/8, 1/4 NPT gauges. We hope the one you receive has all the correct parts. If you buy one, check everything before throwing it in your tool box. I'm a professional mechanic so I'm familiar with threading fittings. Much luck.
