Title: RESTRAINED PLASTIC PIPE JOINT AND METHOD OF MAKING SAME
Abstract:
A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides a restrained pipe joint including a first pipe including a bell with a spigot entryway and a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of restraining segments is at least partially embedded in the gasket.
