Thermaflect Heat Shield Sleeve 3 Inch ID Hook & Loop Seam Heatshield Products


Shield wiring, lines, hoses and cables from radiant heat. Thermaflect Sleeve acts as a thermal-barrier capable of reflecting up to 90 percent of radiant heat (requires minimum of 1 inch airspace and good airflow). It is excellent to use on fuel lines, wiring looms, air intake, intercooler pipes and air conditioner hoses. By keeping fuel and air-intake temperatures cool, it helps to prevent vapor lock, improves performance, increases mileage and reduces fuel evaporation. It weighs a fraction of silicone-coated sleeves and offers superior radiant heat insulation. Thermaflect Sleeve withstands 1,100 degrees F of continuous radiant heat and 500 degrees F direct heat. This heat sleeve is also available in a sewn seam.
