ABSTRACT:
A two-piece compression fitting comprises a driving screw and a symmetrical sleeve adapted to be pre-assembled to a threaded receptacle for later connection of coupling tubing. One end of the driving screw is provided with a thin-wall extension for accepting a central cylindrical portion of the sleeve in a press-fit manner so as to provide and maintain co-axial alignment of the inner bores of the screw and sleeve whereby the coupling tubing can be easily inserted therethrough.
