Shield your wiring, lines, and cables safe from heat, without disassembling them. Thermaflect Sleeve acts as a thermal barrier capable of reflecting up to 90% of radiant heat away (requires minimum of 1" of airspace and good aiflow). It is excellent to use as a fuel line heat sleeve, on 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, improves mileage and also reduces fuel evaporation and vapor lock. Wait there is more; a 3' length our Thermaflect Sleeve weighs less than 6" of the silicone covered stuff of the same diameter. Though it weighs much less, it offers superior radiant heat protection. Thermaflect Sleeve withstands 1100-degrees Fahrenheit of continuous radiant heat and 500-degrees Fahrenheit direct heat. This fuel line heat sleeve is also available in sewn seam. Features: Capable of reflecting up to 90% of radiant heat Helps to prevent vapor lock, lower air intake temperatures, protects wires from melting Made in the USA Installation Tips: Face velcro seam in opposite direction of heat source Be sure ends of sleeve are sealed or secured to component you are trying to protect. You can seal the ends using our Thermaflect Tape, Cool Foil Tape, Thermal-Tie, shrink tube, or any mechanical fastener. Securing the ends will ensure no hot air sneaks in behind the sleeve, thus allowing it to work more efficiently. It also functions better if the heat shield sleeve is tight on the component
