With harder materials like steel however, torque is often transferred from the compression nut to the ferrule as the nut is tightened. Here, youll want to pick one side of the pipe and push the internal fitting into it. Furthermore, compression nuts and ferrules are often all metal, and can be autoclaved, cleaned, or sterilized more easily than fittings containing plastics or internal elastomers.
