I've had problematic compression fittings over the years... Often I
get fed up enough with them and change them to flared fittings... It
seems that with compression fittings, there is a certain amount of
force that you can use to tighten the fitting -- too little and it
will leak, too much and it will deform the fitting and also leak...
With flared fittings, it seems that you can really torque it down and
it won't deform and start leaking... YMMV, of course...
