I think the term "compression fitting" refers to the fact that the
Ferrule fits over the line easily until it is tightened into place. By
tightening the fitting, the ferrule is compressed in place and then
can't be pulled off the end of the line. The other types of fittings
don't actually compress. THey seal by the pressure of the firring
against the flared end of the line.
