    摘要: A gasket for preventing separation of interconnected pipes without damaging the pipes. The gasket includes a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes a row of exposed teeth configured for engaging a spigot end of a pipe and a trough configured for pivotably engaging a bead on a bell. The trough is further configured for shearing or deforming the bead and inhibiting over-pivoting of the segment about the bead when the pipes are partially withdrawn away from one another, for example, during over-pressurization of the pipes.
