A twin-ferrule compression fitting is only as reliable as its smallest parts. When the nut is tightened, the front ferrule is driven into the fitting body to form the seal, while the back ferrule hinges inward to grip the tube and hold it against pressure and vibration. Front ferrules, back ferrules and nuts are listed here individually for building new joints, replacing parts after a line has been cut back, or holding maintenance spares.
Tube plugs and tube caps blank off a line or an unused fitting port. A plug fits into a fitting body in place of a tube and is held by the nut, while a cap closes the end of a run of tubing. Pipe inserts support the inside of soft or thin-walled tubing so the ferrules have something firm to grip, and the table lists their internal diameter alongside the tube OD.
The range is stainless steel 316 and covers imperial tube OD from 1/16" to 2" and metric tube OD from 3 mm to 50 mm. It is good practice to keep ferrules, nuts and bodies from the same fitting system rather than mixing makes.
