Frank it isn't the pressure involved .  It is the conformability of a double 
flare that allows it to seat and compress at an angle if necessary.  (Tube 
not lined up with the cone in the fitting).  They also seat better on a 
damaged cone..  There are some who claim that there is less fatigue at the 
flare juncture with the tube with a double flare.  May be true.  No argument 
from me.  All I want to do is get home, as I have several times with fuel 
lines, and once with a brake line.           Smitty
