Abstract: A reusable insulation jacket for straight industrial tubing, as well as elbow, union, coupling, tee, valve, and other connectors carrying extreme hot and cold materials comprises a thin insulating mat. For straight tubing, the jacket is of a width as to completely wrap the tubing and overlap itself. For tubing connectors, the jacket is stitched and stuffed (manufactured) to form a cavity as to completely receive the tubing connector. In all forms, the jacket will overlap itself whereat complimentary releasable fastening hook and loop material securely hold the jacket in place to insulate the tubing or tubing connector and to prevent an individual from otherwise being burned from contacting the tubing or tubing connector. Additionally, the jacket has properties as to insulate much more efficiently then fiberglass insulation, allowing a much lower profile to accomplish equal insulation characteristics which allows more insulated tubing in a smaller area.
