Al,

That has been my experience, too, right down to the luck factor.  In fact,
the pliers might be better than a flare nut wrench (aka, line nut wrench).

I'm in the midst of changing out some calipers on a car.  Well, I should say
I wanted to change the calipers.  Now, it's the calipers AND the hoses AND the
front hard lines.  Originally I thought -  brass fittings, copper clad lines,
what could be the problem.  Using a flare nut wrench, the first fitting was a
little snug, but it finally broke loose from the caliper.  That was the only
one that backed out with the flare nut wrench, the rest rounded out.  I worked
my way through every penetrant I had in the arsenal, went to heat then
finally made a mess with a pair for vise grips.

Never discount luck.
