摘要

The invention relates to a gasket sealing of tubes designed to be received within a channel provided in the inside of a socket end of one end of the plastic tube of bell female that is mounted with one end of the pipe male coupling to form a union. Of plastic tubes.The channel at the end of the plastic tube of bell female is pre formed during production and the gasket is installed below. The gasket has a portion of the body of rubber, which is reinforced by a hard plastic belt formed as a series of wedges spaced integrals that are interconnected by a flexible tape.The hard plastic strap acts to prevent extrusion gasket during variations of pressure conditions, as well as preventing displacement during assembly of the field.
