What sorta unions do I have?

Hi

Before I started doing the brakes I found some differences in the connectors at the caliper end

The the ones that came out are less concave than the M10 and are a sort of more rounded at the business end.
They are both the same length and have the un-threaded bit at the end.


Does this matter much or what should I be buying? The Pipes are bubble flared.

My RR is a '92 3.9

pipes when made are either convex (stage 1 when your using flaring tool) usually with male fitting or concave (stage 2 ) usually with female fiting

My pipes are convex bubble flare on what appears to be a m10 male nut
