A pipe coupling comprising:

• a coupling body having first and second ends;
• a first pack joint nut located at the first end of the coupling body;
• a second pack joint nut located at the second end of the coupling body;
• wherein the coupling body is made of a first metal material and the first pack joint nut is made of a second metal material;
• wherein the first pack joint nut is configured to receive a portion of a first pipe;
• wherein the first pipe is made of a dissimilar metal material to the first and second metal materials of the coupling body and the first pack joint nut;
• an insulating sleeve configured to line at least a portion of an inner periphery of the coupling body;
• a split insulating gripper sleeve configured to line at least a portion of an inner periphery of the first pack joint nut;
• wherein the insulating sleeve and split insulating gripper sleeve are made of non-metallic materials;
• a gasket located between the insulating sleeve and the split insulating gripper sleeve;
• and
• a flange located on the insulating sleeve to provide a positive stop for the first pipe;
• wherein the insulating sleeve, the split insulating gripper sleeve, and the gasket serve as physical non-metallic barriers between the first/second metal materials of the coupling/first pack joint nut, and the dissimilar metal material of the first pipe.
