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.Features: Continuous operating temperature of 1200 degrees F, 2000 degrees F intermittent Capable of reducing up to 90 percent of radiant heat Helps to prevent vapor lock Lower air intake temperatures Protects wires from melting Hook and loop seam allows installation without component assembly Size: 1 Inch ID x 3 Foot (Hook and Loop Seam) Operational Temperature: 1100 degrees F Peak Temperature (30 seconds or less): 2000 degrees F Color: Silver/Aluminum Material: Proprietary Aluminized Fiberglass Sold As Each Installation Tips: Velcro and Radiant heat barrier Requires 1 inch of airspace Not designed for direct contact Warnings: Always wear safety glasses Dust mask, gloves and long sleeves are recommended when handling this product Caution this material is electrically conductive Be sure to insulate any terminals that might come in contact with this product
