This listing is for a universal brake adapter that will allow you to convert from a M12-1.0 bubble flare to a M10-1.0 female inverted flare. Many new style master cylinders have female bubble flared ports. using this adapter will allow you to adapt to a M10-1.0 inverted flare brake line, if this is your configuration. I am sure there are also many other applications for this adapter as well. If you are unsure of your particular needs please contact me for assistance.

We carry additional size adapters including metric bubble flare to metric bubble flare, metric bubble flare to SAE inverted flare and more. Look at my additional listing or contact me for assistance.
