Claims

[Scope of utility model registration request]

A joint body into which the pipe end of a polyethylene pipe with a stiffener inserted into the pipe end is inserted through a socket at the end and forms a gasket accommodating part, and both ends of the joint main body which are externally fitted onto the polyethylene pipe. and a gasket accommodated in the gasket accommodating portion, and the gasket is biased in the direction of diameter reduction when the joint body and the push ring are tightened relative to each other. In a polyethylene pipe joint that is pressure-welded to the outer periphery of the end of a polyethylene pipe, the outer diameter of the peripheral wall of the stiffener inserted into the end of the polyethylene pipe is larger than the inner diameter of the end of the polyethylene pipe, and A polyethylene pipe joint characterized by having a C-shaped cross section.
