ABSTRACT:
A pipe sealing gasket is shown which is designed to be received within a groove provided within a belled, socket end of a plastic pipe. The groove in the plastic pipe is preformed during manufacture and the gasket is installed thereafter. The gasket nominal diameter exceeds the internal diameter of the belled pipe end. A special installation tool is used to pull the gasket from an initially deformed, elliptical shape to a normal cylindrical shape. The installation tool uses only one fluid cylinder for power and can be hand installed and operated.
