Although I soaked the brake-hose to hard-line nipple-nut with Kroil, and I used the proper 11mm flare-nut wrench, I still managed to strip the nipple/hex-nut and still didn't loosen it.

Any ideas on how to remove?

Should I just purchase a new set of hardlines and cut it out the stripped one?

Thanks in advance,
