Brake line tube nut size

[Diesl Jp]

Installing longer brake lines in the rear. Sadly, one of the factory tube nuts connecting the hard brake line to the flexible hose has ruined threads. Having a helluva time finding what size I need to get for a replacement. I know the hard line size is 3/16 but don't know the correct size for the threaded side. Anybody happen to know?

I figured it out. For anyone that comes across this:
3/16" tube side, M10x1 inverted flare on the thread side. I ended up getting this one from the local auto parts store. Fair warning, they are slightly smaller diameter on the inside than factory, so I had to drill it out to 13/64 to get it to slide onto the hard brake line. Worked like a charm after that, though.

Dude, you're a life saver I thought I was loosing my marbels...That brake line fitting is ridiculous... Find a fitting that goes on the handling but also fits the flex line...omg...THANKS

Tubing wrenches are what you want. Think of a box end wrench with a slot cut in it enough to have the tubing go in it.
