The 1/2"-20 end has longer threads required to fit some OE (Original Equipment) and aftermarket Mopar and GM master cylinders. Most other adapters will bottom out before they seal on the inverted flare. Steel adapters are recommended on all brake systems since they are stronger and can handle higher pressures.
