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.

1. A system for sealing a spigot, the system comprising: a gasket, the gasket having a front end, a first section, and a second section, the gasket defining at least one groove in the first section;at least one substantially rigid member contacting the front end, the substantially rigid member made
1. A system for sealing a spigot, the system comprising: a gasket, the gasket having a front end, a first section, and a second section, the gasket defining at least one groove in the first section;at least one substantially rigid member contacting the front end, the substantially rigid member made of a material that is more rigid than a material of the gasket; anda bell encircling the gasket, the bell defining a gasket seating area, the bell including an inner surface, wherein the inner surface includes a blended curve and contacts the at least one substantially rigid member, wherein the blended curve includes at least one paraboloid. 2. The system of claim 1, wherein the gasket defines an insertion groove. 3. The system of claim 2, wherein the insertion groove is defined at the joining point of the first section and the second section. 4. The system of claim 2, wherein the insertion groove mates with an extended lip of the bell. 5. The system of claim 1, wherein the bell includes an extended lip. 6. The system of claim 5, wherein the extended lip is proximate the gasket seating area. 7. The system of claim 1, wherein the gasket includes a gasket heel, and wherein the gasket heel mates with the gasket seating area. 8. The system of claim 1, wherein the substantially rigid member includes teeth. 9. The system of claim 1, wherein the spigot includes an end and wherein the end includes a quarter ellipse portion extending from an outermost surface of the spigot radially inward and axially inward, the quarter ellipse portion defining a fillet in the end of the spigot. 10. A system for sealing a spigot, the system comprising: a gasket, the gasket having a front end, a first section, and a second section, the gasket defining at least one groove and at least one insertion groove;at least one substantially rigid member contacting the front end, the front end between the at least one substantially rigid member and the first section, the substantially rigid member made of a material that is more rigid than a material of the gasket; anda bell encircling the gasket, the bell defining a gasket seating area including an extended lip, the bell including an inner surface, the inner surface defining a blended curve, the blended curve including at least one paraboloid and contacting the at least one substantially rigid member;wherein the extended lip and the insertion groove are arranged in mating relationship. 11. The system of claim 10, wherein the insertion groove is defined at the joining point of the first section and the second section. 12. The system of claim 10, wherein the spigot includes an end and wherein the end includes quarter ellipse portion extending from an outermost surface of the spigot radially inward and axially inward, the quarter ellipse portion defining a fillet in the end of the spigot. 13. The system of claim 10, wherein the at least one groove is defined in an upper surface of the first section, the upper surface facing radially outward.
