Feature●Thermo-Sleeves ultra light-weight construction provides more insulating than traditional bulky rubber-coated fiberglass●The aluminized sleeving reflects over 90 per cent of radiant heat, and is fireproof and oil resistant●The Thermo-Sleeve can handle conductive heat temperatures of 750 degrees Fahrenheit and radiant heat temperatures up to 2000 degrees Fahrenheit●Typical applications include brake, fuel, oil and a/c linesDescription The new lamination of a high-temperature fabric to a highly-reflective foil is the makeup of Thermo-Sleeve which provides protection from radiant heat for hoses and wires. Thermo-Sleeves ultra light-weight construction provides more insulating than traditional bulky rubber-coated fiberglass.
