Abstract
Gaskets for use with a bell and spigot coupling system are disclosed herein. The gasket comprises an elastomeric member having a front edge, a first section, and a second section. Axial forces generated by the insertion of the spigot to the first section of the elastomeric member displace the first section of the elastomeric member in an axial and radial direction.
