Vacuum insulated structure with end fitting and method of making same

A vacuum insulated structure comprising:

• a tube having an outer wall;
• a jacket surrounding the tube to enclose an annular insulating space between the tube and the jacket,
• the jacket having an end that terminates adjacent to the outer wall of the tube, and the jacket being brazed to the outer wall of the tube;
• so as to form a seal formed between the jacket and the outer wall of the tube to preserve a vacuum within the insulating space;
• and
• a fitting affixed to one of the tube and the jacket for coupling the vacuum insulated structure to an external device,
• wherein the fitting is affixed to an inner wall of the tube.
