Valco stainless-steel ferrules for 1/32”, 1/16”, and ⅛” OD tubing are an excellent fit for all standard Valco internal fittings and most valves, or with those of most other manufacturers. These metal ferrules cut a ring near the end of the tube, preventing tube release at high pressures without significantly deforming and restricting the tube interior. (However, if the hardness of the tubing is equal to or greater than that of the ferrule, the result is more likely deformation of the tube rather than a cut ring.)
