surfaces. These flare connections will not benefit from being un-done and
re-done.

Hmmm, Are you sure about that?
That type of connector is VERY (I repeat, VERY) expensive.
The brand name I'm familiar with is 'Swagelock'.
They were good to 100K PSI.

Only thing was, they were only good for a connection once.
The connection depended on the fact that the 2 surfaces of the
connection soft-welded together.

I still remember the spec for a SwageLock connector (I still have one
somewhere):
Turn down until finger tight.
Then 1/4 turn to make the seal. (Hmm or was it 1/2 turn)

Good to 100K PSI.

At least that's how I 'rember it.
(someone will prolly correc me on info that is older than I care to admit.
Hmmm, was it 1/4 turn or 1/2 turn?

PS:
Don't try to use the flare fitting twice.
Once the fitting is soft-welded, if you break it, it's good for a slow leak.
