Heatshield’s Lava Tube thermal-barrier sleeve is designed to protect fluid lines from heat exposure, prevent vapor lock and shield wires from heat damage. The sleeve is made from a specially-formulated proprietary volcanic rock-based cloth engineered to withstand continuous heat of 1,200 degrees Fahrenheit and up to 2,000 degrees F of intermittent heat. The sleeve’s fibers are designed for added durability to help resist abrasions and chemical exposure. A high-temperature hook-and-loop fastening system helps simplify installation, including on lines, cables, wiring bundles and linkages. The sleeve is available in four diameters ranging from ½ to 1½ inches and in lengths of three and 10 feet that can be cut to fit.
