Abstract
A resin pipe joint comprising a tapered flare portion ( ) formed on a pipe ( ), an inclined portion ( ) formed internally of a joint body ( ), an annular member ( ) having inner peripheral surface fitted on the pipe ( ) and the outer peripheral surface inserted in the joint body and formed at the end with a tapered chamfered portion ( ), and a pipe clamping member ( ) threadedly fitted to the joint body ( ). The pipe clamping member ( ) being threadedly fitted to the joint body causes the chamfered portion ( ) of the annular member to pressure-contact the flare portion ( ) of the pipe and the flare portion of the pipe to pressure-contact the inclined portion in the interior of the joint body, whereby the clamping force can be concentrated on the flare portion of the pipe, so that a high sealing capability between the pipe and the joint body is obtained.
