ABSTRACT:
This invention relates to a pipe seal or joint, and refers especially to a seal between an inner tubular surface and an outer tubular surface. The invention is concerned particularly, but is not limited, to seals of the O-ring or D-ring type employed in the joining of concrete pipes, for example for use between the spigot of one pipe and the socket of an adjacent pipe. The invention is applicable to the seals or joints between inner and outer tubular surfaces, such as pipes or other members, in which a sealing member is located in a recess formed in the outer surface, or in the body forming the outer surface.
