Claim:
1. A pipe connector fitting comprising: a) a cylindrical body disposed along a longitudinal axis, the body defining an inner wall, the body having a throat centered along the longitudinal axis between an upstream end and a downstream end thereof; b) a bore defined by the inner wall of the body; c) a threaded annular metal insert disposed within the body; d) an elongate gasket comprising a hook-shaped cross-section when un-compressed; and e) a recessed gasket retention area comprising (i) an annular gasket retention surface disposed in the body and aligned perpendicularly to the longitudinal axis of the body, and (ii) a lip extending longitudinally from the retention surface, the recessed gasket retention area and the lip being sized and dimensioned to accept and retain the elongate gasket to prevent the elongate gasket from moving from the recessed gasket retention area into the throat of the body; wherein, the elongate gasket is disposed within the recessed gasket retention area; wherein, when a threaded male fitting is threadedly disposed within the body, the threaded male fitting can be rotated within the downstream end of the body 360° while remaining continuously fluid tight for pressures in excess of 300 psig; wherein the threaded annular metal insert has a step diameter with a larger internal diameter portion longitudinally closer to the recessed gasket retention area than a smaller internal diameter portion; wherein the elongated gasket extends longitudinally from the recessed gasket retention area through the larger internal diameter portion and abuts the smaller internal diameter portion; and wherein the elongated gasket extends radially inwardly beyond the smaller internal diameter portion.
