ABSTRACT:
A piping structure and method of manufacture allow for the mechanical joining of two piping products as well as the hydraulic and mechanical sealing thereof by means of an elastomeric gasket having an integral pressure transference device. A socket is produced in one pipe product along with an integrally formed interlock means and the gasket. A spigot is produced in another pipe product along with an integrally formed interlock means complementary to the socket interlock means. The gasket is situated within the socket adjacent a tapered wall portion of the socket and is compressed by a tapered portion of the spigot. In a preferred form, the piping product is formed of a thermoplastic wherein the socket and spigot are easily formed after initial production of the piping product. However, the present joining system is not limited to after product formation and may be utilized for a variety of piping materials and methods of manufacture.
