I'm from Europe and reuse bubble flared lines all the time with NO PROBLEMS. No leaks for years.

very nice video...you explained well thanks

[@spelunkerd]

So, does that mean that if I have to undo a bubble flare brake line connection, I would have to make a new flare before I can be confident it will not leak?

[@rheniformer]

Thank you for the excellent photos and illustrations. Very helpful!

[@bolter99]

Yes.

[@timramich]

Yeah, I've never heard of a bubble flare being ruined once they are undone.

[@pawe9928]

yes, you always have to make a new flare. It is brake system...it is your and the others safety... better is always make a new flare than risk with the old one

[@JohnBarbourJr]

Yup! Once the bubble is connected and tightened, it is done. The bubble flare is kind of like a double flare but the "doubling" is achieved when you tighten the fitting. It will no longer be able to "crush conform" to the connection point again.
