As far as leaking flared joints, 45 degree conical copper washers have been used for years to seal between leaking 45 degree fittings. Several years ago an a/c auto shop installed 2 in the a/c lines in a vehicle I owned to stop leaks at the 45 degree joints. I and the next owner who is a friend never had another a/c leak.
