Abstract
The present invention provides a fitting mechanism capable of distributing pressure applied on an outermost layer of plastic, and contributing to cooperation and complementary reaction between a fitting body and a ferrule body under severe temperature change. A fitting mechanism according to the present invention comprises a fitting body formed of metal, and a ferrule body formed of metal, wherein the fitting body is coupled to the ferrule body by fastening the third threaded portion of the ferrule body with the second threaded portion of the fitting body, and the fitting body slope surface is impinged onto the ferrule body slope surface forming a fluid tight contact and causing the ferrule body deformation portion to be deflected inwardly, tightened around and penetrate into outermost layer of plastic, and the outermost layer of plastic of the leading end of the multilayer composite pipe impinges onto coupling end portion.
