Designed to be the ultimate protection for your cables, lines, wire or hoses. DEI's Ultra Sheath MA™ Extreme Heat line & Hose Protection has a high sustained heat capability of up to 1100°F and is more flexible than standard foil or bonded aluminum sheathing products. It is manufactured using a process that impregnates molten aluminum to the core fabric. This gives a finish product that has higher heat reflective properties. It is the best choice for tight high heat applications that require the maximum protection.
