Abstract
A pipe joint has a body, and an annular packing is mounted to the opening of the body into which a fluid tube is inserted. The packing is provided with: a body section having a substantially rectangular cross-sectional shape; and a seal section protruding in the radial direction from the inner peripheral surface of the body section. The seal section is formed at substantially the center of the body section in the widthwise direction thereof and is formed in a triangular cross-sectional shape tapering to the inner peripheral side. When the fluid tube is inserted in the opening, the seal section of the packing makes sliding contact with the outer peripheral surface of the fluid tube.
