More Information
Summary:The invention relates to a high-pressure pneumatic plugging device for pipes, formed by an outer covering of a tubular rubber body (2), at the ends of which there are coupled a key (3) and an inflation connector (4), attached to one another by means of a flexible rod (5) preventing the longitudinal increase thereof when it is inflated. The rod (5) has a plastic covering (6) to stiffen and protect the tubular rubber body (2). The threaded body (3b) of the key (3) emerges through the hole (7) of the tubular body (2), coupling a receptacle-like part (9). A ring (11), fitted to a perimetric flange (12), protects the other end of the tubular rubber body (2) maintaining its tightness.
