Assembly technology: internal swaging – an internal swaging system provides reliable and safe fitting-hose connection. It ensures full and unrestricted flow through the fitting of a flexible hose assembly. The system utilizes a cold forming method. Here, a hardened, cone shaped swaging tool is used. Its diameter in the widest, working part is slightly bigger than the internal diameter of the fitting before crimping. The tool is pulled down the inside of the fitting so it expands to a desired diameter. The tail of the fitting extends the hose and thus compresses it against the ferrule. The main advantage of internal swaging over external crimping is the increase of a flow rate. When internally swaged, the inside diameters of both the hose and its fitting are the same.
