This adapter in the concave version will be excellent for adapting between common 3AN flexible brake line to the standard and common metric bubble flares that will make up the rest of the system in my race car. Pegasus is excellent in terms of a resource to find the little adapters that custom race car applications need. In this case I'm going from a factory booster/master AND 3 channel ABS system to a next gen 4 channel system with dual masters and a balance bar. Adapters like this make it easy.
