Patent attributes
A universal pipe connector for forming a connection with at least one pipe end includes a connector body having an opening for receiving the pipe end. A clamping ring, extending around, and mechanically engaging, the opening, features a tightening mechanism for tightening it between a first maximum diameter and a second minimum diameter which differ by at least a length d. An annular sealing element is deployed around an inner surface of the clamping ring for sealing around the pipe end. The sealing element is formed with a primary inner surface and at least one roughly cylindrical coaxial layer of thickness ½ d. The layer is connected to the primary inner surface by a readily severable connection such that, by selectively removing the layer and tightening the tightening mechanism, the pipe connector forms a sealing connection with pipes having diameters varying over a continuous range of at least 2 d.
