Abstract
A molded annular gasket is placed upon a mandrel for embedment of its annular-shaped embedment portion within an opening in a cast member. After the cast member has been cured and removed from a molding assembly, including the mandrel, the pipe attachment end of the gasket is pulled through the center of the gasket so that its pipe attachment end extends beyond the embedment end, to facilitate the placement of a take-down clamp which secures the pipe attachment end to a pipe inserted there through thereby providing a fluid-tight joint. The mandrel is preferably a one-piece member. The gasket may have a cylindrical or conical-shaped intermediate portion provided with spaced-apart annular projections at the pipe attachment end, between which the takedown clamp is arranged.
