ABSTRACT:
A symmetrical elastomeric seal for providing a fluid-tight joint in the annular space between the spigot of one pipe and the bell of an adjoining pipe. The gasket includes tapered ribs projecting from an annular web with their peripheries forming a continuous raised rim. The ribs are symmetrically tapered about axially-spaced parallel planes. A clamp may be installed between adjacent ribs to positively secure the gasket on the spigot. The hardness of the elastomer in the web relative to the ribs may vary according to the fluid pressure of the joint.
