Abstract
A pipe sealing assembly for sealing a connection between a pair of pipes. The sealing assembly includes a generally cylindrical seal or gasket having a pair of axially spaced sealing portions joined by a bridge portion. Each sealing portion has a plurality of compressible sealing ridges, as well as an annular expansion band seat capable of receiving the expansion band of an expansion band assembly that is used to sealingly compress each sealing portion against a respective inner surface of a pipe. Additionally, each sealing portion may include a hollow section which houses the expansion band assembly, and may be provided with a small slit for installing the expansion band assembly and allowing access to the expansion mechanism of the expansion band assembly during installation, or a separate cover member for enclosing the expansion band assembly.
