Abstract
A gasket for a pipe joint includes an annular gasket body which is symmetrical around an axial centerline and is therefore insensitive to axial orientation. The gasket is formed of a resilient material and includes a base adapted to sealingly engage an annular groove formed in one of the pipe segments to be joined. First and second protrusions run along the length of the gasket body and extend radially therefrom. The first and second projections are spaced apart symmetrically about the centerline. An annular bore, bisected by the center line, extends within the interior of the gasket body, and comprises a central region bridging first and second transversely spaced apart lobes. It is particularly suited for sealing an annular space in a bell-and-spigot pipe joint and provides an increased surface contact area to compensate for defects in the sealing surfaces of the pipes.
