Foam Insulated Liquid Nitrogen Transfer Lines

An economically and practical solution for transferring Liquid Nitrogen exists where double-wall insulated tubing is commercially available. This application eliminates the need for the more expensive and fixed Vacuum Jacketed alternative. Just simply cut and reconnect with compression fittings or solder joints. The foam can be slit, glued, and taped for seamless and frost-free joints.
