Claim of US Patent No. 10,215,316

1. A plumbing connector comprising:a fitting having a first end and a second end and having external threads on at least the first end;
a tube having a first end and a second end, the first end of the tube inserted into the first end of the fitting;
an annular gasket coaxial with and surrounding an outer diameter of the tube and adjacent the first end of the fitting;
a compression ring coaxial with and surrounding the outer diameter of the tube and adjacent the gasket, the compression ring having an inner edge and an outer edge; and
a lock ring coaxial with and surrounding the outer diameter of the tube and adjacent the compression ring, the lock ring having an inner edge and an outer edge;
a nut coaxial with and surrounding an outer diameter of the tube and having internal threads adapted to engage the external threads of the fitting, the nut adapted to contain the gasket, compression ring, and lock ring upon threading of the nut onto the fitting via the internal threads of the nut and the external threads of the fitting,
wherein, upon threading of the nut onto the fitting via the internal threads of the nut and the external threads of the fitting and tightening of the nut, the gasket is compressed, the inner edge of the lock ring bitingly engages the outer diameter of the tube, the gasket forms a seal with at least the first end of the fitting, the outer diameter of the tube, and the outer edge of the lock ring, and contact between the compression ring and the lock ring deforms the lock ring pushing the inner edge of the lock ring into a biting engagement with the outer diameter of the tube and the outer edge of the lock ring into a sealing engagement with the gasket, and the compression ring is spaced apart from the tube.
