don't you hate it when that happens?

you didn't need to.  once the wrench slipped and rounded the tube nut,
you would have had to redo the line anyway.  in order to remove the
tube nut and install a new one, you have to cut off the flare.

they are definitely not inverted flare.  you want the ISO flares.
if you already got it off, you can verify this by examining the line
closely.  it should be a smooth rounded flare (hence the name
"bubble flare".

you can also ask on birabrakes.

what are you replacing the old hose with?

i'd say this is a good time to switch to AN flares.  get a 37 degree AN
flaring tool, and set it up for 3AN.  then you can attach the braided
steel hose directly to the line without having to use an adapter.
