Abstract
A self-flaring fitting assembly for semi-flexible, convoluted tubes or pipes is provided. The inventive fitting assembly, which basically comprises an adaptor, a nut, and a split bushing assembly, eliminates the need for sealing gaskets, is reusable, and further facilitates the ease and speed of installation of semi-flexible piping systems. When used with jacketed tubing, the present inventive fitting assembly is capable of both preventing the undesirable movement of the jacket during installation and assembly and of reducing or eliminating exposure of the tubing located within the fitting assembly to contaminants or corrosive materials found in the surrounding environment.
