ABSTRACT:
A restrained sleeve coupling assembly for interconnecting pipe sections includes a generally cylindrical sleeve body, a generally cylindrical adaptor body and opposed end rings which are sleeved over the respective pipe sections to be joined. The generally cylindrical sleeve body has opposed gasket engaging surfaces adjacent opposite ends of the sleeve body for receiving fluid sealing gaskets forcibly engaged with the sleeve body, the adaptor body and one of the opposed end rings. The adaptor body includes a gasket engaging surface for receiving a fluid sealing gasket forcibly engaged with the adaptor body and the other of the opposed end rings. The end rings include flanges for engagement with elongated tension bolt assemblies to secure the sleeve body, the adaptor body, the gaskets and the end rings in assembly with each other.
