  • Folded gasket and method of casting same in a wall
    Patent number: 5876039
    Abstract: A folded annular gasket is cast into an opening in the wall of a manhole and held in a compressed state by an annular support. The annular support includes a helical strip which can be stripped apart to remove the annular support from within the annular folded gasket. A pipe to be connected to the manhole is inserted into the annular support. After the pipe is inserted in the annular support, the annular support is stripped out from between the folded annular gasket and the pipe. Removal of the annular support causes the folded annular gasket to press against the pipe and thereby form a seal. Removal of the annular support can also cause the folded annular gasket to invert. The inverted part of the annular gasket can be clamped to the pipe and function as a boot or sleeve.
