Claims

[Scope of utility model registration request]

In a seal ring of a pipe joint made of a rubber elastic body, which is inserted into the inner circumferential surface of the end of a metal pipe joint which is connected to the pipe by fitting the metal pipe and compressing the end in the radial direction. , at least one or more recesses or protrusions are provided along the inner diameter side or outer diameter side of the seal ring in a cross section perpendicular to the axis of the seal ring, and the recess or protrusion is perpendicular to the axis. A seal ring for a pipe joint that is symmetrical about a central axis.
