I don't want to give anybody a high degree of confidence in a repair like this, because if done improperly, it can be dangerous. And compression fittings are MUCH easier to do improperly.

But I've seen small compression fittings like this handle well over 5000psi. Average brake line pressure is about 700psi, with peaks nearing 2000psi during hard braking. I might risk a repair like this if I had no other options (and replace as soon as possible).

However, if I was going to take a guess, if you DID manage to get a good fitting capable of 5000psi, I'd estimate it would drop to less than 1000psi if you pull it apart and re-assemble it.
I have to agree 100% as said can be inspection fail or illegal. Because some people can't do some thing right or should not. Ever one learns from the +"s & the -"s people make or should.
