These fittings arent normally used in new constructions but rather, renovation projects. Torque, on the other hand, can vary greatly, depending on fitting and ferrule material, lubrication, degree of galling (for stainless fittings), and other factors. But besides knowing how to install a compression fitting on plastic tubing, you must learn how to seal the fittings too. Bevel the edges of the pipe with a file. The tape prevents leaks by compensating for the different expansion rates of brass and plastic. Tighten the tool slightly, and rotate once or twice in both directions again.
