ABSTRACT:
A resilient gasket adapter to form a tight seal between pipes, said gasket having a plurality of projections which interact with cooperating pipe structure to retain the gasket in position as pipes are joined. This gasket overcomes the problem of fishmouthing, a situation in which a gasket is pushed out of a retaining groove as pipes are joined.
