ABSTRACT:
A pipe gasket includes a toroidal gasket body and projections extending away from a peripheral surface of the gasket body. The gasket body is configured to allow the gasket body to roll along a spigot end of a first pipe as the spigot end is received inside a bell end of a second pipe. The projections each include a first surface and a second surface. The first surface is configured to facilitate rotation of the gasket body in a first rotational direction. The second surface is configured to inhibit rotation of the gasket body in a second, opposite, rotational direction.
