Description
The BrakeQuip BQ44 adapts an M10 x 1mm thread to an M12 x 1mm thread, letting a brake line, caliper, or master cylinder port built to one of these common metric sizes accept a fitting built to the other, without swapping the whole line or the component it threads into. Useful when replacing a caliper, master cylinder, or proportioning valve with an aftermarket part that doesn’t match the original port thread.
