With harder materials like steel however, torque is often transferred from the compression nut to the ferrule as the nut is tightened. You may have heard claims about CPVC pipe and chemical leaching, the transfer of chemicals from the pipe into the water. Torque, on the other hand, can vary greatly, depending on fitting and ferrule material, lubrication, degree of galling (for stainless fittings), and other factors. Insufficient tightening of the compression nut will not deform the ferrule enough to create this contact, but over-tightening will deform the ferrule too much, creating a surface contact. Caution: Wear special solvent-proof gloves for extensive work. tubing and 1-in.
