ABSTRACT:
A method for manufacturing a device for the magnetic treatment of fluids including water, liquid and gaseous fuels, propane, oil and the like. An elongate inner tubular casing having a magnet therein is supported within an intermediate casing made of a ferromagnetic material, and a pair of end fittings are connected to opposite ends of the intermediate casing and serve to center the inner casing therein. The end fittings each have a tapered passage therein, and as they are threaded on the ends of the intermediate casing, the ends of the inner casing are guided into the tapered passages and are gradually deformed inwardly thereby so that the tapered passages tightly seat against the ends of the inner casing to prevent radial and axial movement of the inner casing relative to the end fittings. This results in a self adjusting support of the inner casing and avoids crimping or other deformation which may result if the end fittings are threaded too far.
