The Basics of Compression Fittings - Beswick Engineering
Most basic compression fittings contain a single ferrule. Single ferrule designs minimize the total number of components, and work reliably when fabricated from softer materials (plastic or brass for example). With harder materials like steel however, torque is often transferred from the compression nut to the ferrule as the nut is tightened.
