Compression fittings use a nut, a plastic compression ring, and a seal to create a tight seal on any pipe. Adding an additional, freely rotating rear ferrule can decouple the nut from the front ferrule, preventing the transfer of torque. 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. Keep in mind that a crooked cut will have less surface area to cement and a greater chance to leak. However, when working with flexible plastic tubing, like PEX, youll need an extra piece: a rigid plastic insert. You can also use a stab-in tee to connect PEX fittings supply to CPVC.
