Great part.

These brake line adapters work great when going from an AN 3 or AN4 stainless steel brake line to your hard brake lines. They also fit into the mounting tabs perfectly. ..makes for a very clean install. I use these on all my builds...front and rear. Don't waste your money on those through frame fittings, that is a great place for air pockets hang out and almost impossible to get out resulting in soft brake pedal. Buy these and the weld on tabs...

Cheap product

These strip out if you tighten them too much but leak if you don't tighten them enough.
