Abstract

See full text

A pipe joint is provided with a pressing ring, a pipe or a pipe joint body having a containing section, a tightening element, and a packing ring compressed by being pressed by the pressing ring moved by the operation of the tightening element. The packing ring includes a base section fitted and mounted in the containing section at a rear thereof, a seal section contained within the containing section at a front thereof, and a connection section which connects the base section and the seal section and has a cutout groove. When the packing ring positioned by fitting and mounting the base section in the containing section at the rear thereof is subjected to pressing by the pressing ring, the seal section is bent into the cutout groove and is deformed, and compression caused by the deformation creates a sealed state.
