する管継手。[Claims for Utility Model Registration] A groove in the circumferential direction is provided at the end of the pipe to be connected, and a retaining ring having one end of the circumference cut out is fitted into the groove,
A retaining ring locking groove is provided from the center wall of the cap nut to the inner surface of the end portion, and has a length to receive the retaining ring, and has a locking step with the retaining ring at the end. In a pipe fitting, a packing is attached to the end of the fitting body by screwing into a thread formed in the fitting, and is compressed between the fitting body and the surface of the pipe via a retainer attached to the end of the fitting. The length from the end of the joint body to the end of the retaining ring when the pipe is inserted and the gasket, retainer, and retaining ring are attached is A, the cross-sectional height from the outer diameter to the inner diameter of the retaining ring is B,
The bottom diameter of the concave groove provided on the surface of a tube with an outer diameter of D is E, the length from the center wall of the cap nut to the center end that screws into the joint body is A, and the retaining ring is locked from the center wall of the cap nut. Assuming that the length of the groove to the locking step is B, the inner diameter of the retaining ring locking groove of the cap nut is C, and the pitch of the screws between the joint body and the cap nut is P, then A≦I ...... A+B≧ A+P... C<D+2×B... C≧E+2×B... A pipe joint characterized by being shaped to satisfy each of the above formulas.
