NOT very tight if it's a flare fitting .   

A compression fitting with ferrule is not as reliable. Ferrules can never be reused once they have been compressed

Finger tight, and then just a tiny bit more.  The shape of the fitting is what seals, not the torque of the nut.  Too tight and you ruin the fitting.

Again, it's the shape of the metal-metal interface that seals, not jamming the nut on super tight.

The IP creates high pressure, much like brakes in a automobile.   
Steel brake lines also use this sort of fitting, but since it's harder steel, it's more difficult for DIY at home, often it's easier/safer/reliable to but the pre-shaped line.

Hi Mike90045

Many thnks for reply, but is not that torque I mean. It's the (20) tighten in the body (1). It took some strength to unscrew it, I say quite a bit.

the body BRYCE is Aluminium.

Now I need the toque limit to tight.
