Abstract
A conduit coupling system for use with a spigot includes a bell and a sealing device. The bell is adapted to mate with the spigot. The bell includes a first end and a second end. The bell has a concave annular inner surface and a diameter of the annular inner surface adjacent to the first end of the bell is greater than a diameter of the annular inner surface adjacent to the second end of the bell. The sealing device includes a locking segment including a convex outer surface and a K-type gasket coupled to a locking segment or a non-restraining anti-extrusion segment. The sealing device is adapted to fit between the bell and the spigot.
