A plumbing connector comprising: a fitting (24) having external threads (30) on at least the first end; a tube (32) having a first end (34) inserted into the first end of the fitting; and an annular gasket (38), a compression ring (40), a lock ring (46), a friction ring (68) and a nut (52) coaxial with and surrounding the outer diameter of the tube. The nut has internal threads adapted to engage the external threads of the fitting and is adapted to contain the gasket, the compression ring, and the lock ring upon threading of the nut onto the fitting. Upon threading and tightening of the nut onto the fitting, the gasket is compressed, an inner edge of the lock ring bitingly engages the outer diameter of the tube, and the gasket forms a seal with at least the first end of the fitting, the outer diameter of the tube, and an outer edge of the lock ring, wherein the friction ring (68) is placed between the gasket and the compression ring and the friction ring (68) has an outer diameter smaller than an outer diameter of the lock ring (40).
