Abstract:

A pipe joint includes an outer pipe and an inner pipe inserted into the outer pipe. One of the outer pipe and the inner pipe includes an annular groove and a gasket is positioned in the groove to provide a seal between the outer pipe and the inner pipe. The gasket includes an annular gasket body formed of a resilient material with the gasket body having a centerline. A projection extends radially away from the gasket body. The projection is so located on the gasket body that it is bisected by the centerline thereof. An annular bore extends in the gasket body. The bore is spaced from the projection and is so located in the gasket body that it is bisected by the centerline thereof. The gasket is symmetrical around an axial centerline and is therefore insensitive to axial orientation. It is meant for sealing an annular space in a bell and spigot pipe joint and is capable of sealing against both internal and external pressures and internal and external vacuums.
