The Accu-Fit Centralizer is designed for small diameter thin-walled pipes. Allows you to connect pipes smoothly and precisely. The centralizer is made of high quality stainless steel. The clamping jaws of the centralizer work independently of each other, therefore, with different diameters, the pipes to be welded are aligned relative to the central axis. The centralizer is ideal for orbital welding. Provides enough free space between clamps (73 and 121 mm) for most orbital welders.
