Abstract: A conduit coupling system, sealing device, bell and method of use are disclosed herein. The system comprises at least two piping components, and a sealing device. A first component has a bell and a second component has a spigot, the spigot is adapted to mate with the bell. The bell comprises a first end and a second end, the first end coupled to the first component. 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 comprises a locking segment comprising 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.
