A vacuum insulated structure including a tube having an outer wall, a jacket surrounding the tube to enclose an annular insulating space, the jacket having an end that terminates at the outer wall of the tube, a seal formed between the end of the jacket and 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. A method of making a vacuum insulated structure including forming a tube and a jacket, positioning the jacket over the tube to form an annular insulating space, with an end of the jacket being positioned adjacent to an outer wall of the tube to form a vent, causing air to escape through the vent, sealing the vent, and affixing a fitting to one of the tube and the jacket.
