A pipe gasket is positioned within a pocket in a socket portion of a first end of a first pipe and the end of a spigot pipe is inserted into the socket with the gasket sealing the gap between the pipes. The gasket in one form comprises a blunt rounded nose portion, a central body portion with an insert embedded therein and a rear sealing portion comprising first and second projections, such as fins, that diverge and respectively engage the first pipe and the second pipe.
