The present invention relates to a pipe joint made of resin used for laying pipes in which a high-purity liquid, ultra pure water or the like flow. According to the pipe joint of the present invention, a sealing surface pressure is generated in both axial and radial directions, providing thereby an excellent sealing property for a long period, and facilitate controlling a torque for fastening a pushing ring. The pipe joint made of resin according to the present invention comprises a joint body having a receiving port, a cylindrical portion, an annular groove portion and a stepped surface. An inner ring forcedly inserted by the pushing ring is provided with an outer projection, an inner projection and an annular recessed portion. On at least one portion among axially opposed portions of each surface, an axial sealing portion is disposed. On at least one portion among radially opposed portions of each surface, an radial sealing portion is disposed. The joint body, the inner ring and the pushing ring are individually made of an optional synthetic resin selected among PFA, PTFE, ETFE, CTFE, and ECTFE.
