Claim:
A system for sealing a spigot, the system comprising: a gasket, the gasket having a first section and a second section, the first section axially adjacent to the second section and defining an upper surface facing radially outward and an inner surface facing radially inward, the second section including an annulus pocket and a gasket heel, the gasket heel defining a heel surface, a first shoulder surface, and a second shoulder surface, the heel surface facing radially outward, the heel surface cylindrically-shaped and radially outward from the upper surface of the first section, the first shoulder surface extending radially inward from the heel surface towards the annulus pocket, and the second shoulder surface distal from the first shoulder surface and extending radially inward from the heel surface towards the upper surface, the gasket defining at least two expansion and contraction grooves in the upper surface; and a plurality of substantially rigid members contacting a front end of the first section, the plurality of substantially rigid members made of a material that is more rigid than a material of the gasket, wherein the second section includes a lip seal, the lip seal at a back edge axially opposite from the front end.
