Hi

To aluminium tubes conexion (1/4 or 3/8"), should be applied same torque as copper ? Any special recommedation when dealing with aluminium ?

I imagine copper is better but I want to try aluminium.

The torques that we use for Aluminium are:
20 NM for 1/4"
30 NM for 3/8"
It is recommended that an Aluminium flare nut is used and a small ammount of thred tape is placed on the thread only to prevent galvanic corrosion, if you use a Brass nut then a self adhesive heat shrink should be applied to cover the whole joint.
