Great product as always from Allstar. Mage sure you use a flare nut wrench to avoid stripping these.

The flare nuts worked fune and were near perfact. every single one fit on the tube fine. The threads were good as well and they didn't seem to soft or "roundable" they also fight the wrench tightly which is good for not rounding them! The only thing I noticed was that on the inside hole their was extra coating 2/3 the way up from the starting point of the thread how ever functionality was not affected. Perhaps the threads get an extera coat while the hex does not as to not effect tolerences to fit the wrench. I dont know...

I needed this for brake line repairs on an older vehicle and they worked great.
