Was watching and old episode of ATOH the other day and Rich was with
an AC guy in Florida. They were installing AC in a garage. To make
the connections the guy just flared the pipe and tightened them down.

I know on cars brake lines will leak if you don't double-flare them.
Is the pressure in an AC system that much lower that a single-flare
won't leak?

Brake lines are steel or stainless steel and a lot less ductile than the
copper refrigeration tubing used for air conditioning systems. I'm
assuming the double flare is necessary because the harder material may
crack if a single flare is used and may not be as strong or suitable for
the higher pressures involved in high pressure systems of any type.
