Banjo brake line washers

I did try " seating" or working the banjo and bolt. I believe that I deformed the banjo when I over torqued it the first time, but I got tired of messing with the damn thing. I would rather screw the hose onto a nipple and be done with it. Copper washers don't get it. Will be ordering a pkg or two of the washer that worked, now that I know how to get them.
