Abstract
A joint body has tube connection holes each having an inner circumferential surface including a plurality of contact walls, which are equiangularly spaced about an axis of the tube connection hole and extend along the axis. A joint guide is cylindrical and includes a barb on its outer circumferential surface. The joint guide is configured such that, when the joint guide is press-fitted into the tube connection hole, the outer circumferential surface of the joint guide comes into contact with inner wall surfaces of the contact walls and the barb catches the contact walls.
Claims9
A pipe joint including a joint body having a tube connection hole receiving a retaining ring that is to retain an outer circumferential surface of a tube placed in the tube connection hole, a cylindrical release member that is to release the retaining ring to stop retaining, a cylindrical metal joint guide that guides the release member, and a packing that is to seal between an inner circumferential surface of the tube connection hole and the outer circumferential surface of the tube,
- wherein the joint guide includes on an outer circumferential surface thereof a barb that prevents disconnection, and is press-fitted in the tube connection hole, and
- wherein the inner circumferential surface of a portion of the tube connection hole that holds the press-fitted barb of the joint guide includes a plurality of contact walls each having an inner wall surface in contact with the outer circumferential surface of the joint guide, the contact walls are equiangularly spaced about an axis of the tube connection hole and extend along the axis, and the barb catches the contact walls.
