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% radiant heat away (requires minimum of 1" of airspace and good airflow). It is excellent to use on your 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, improves mileage and also reduces fuel evaporation and vapor lock. Weight 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°F of continuous radiant heat and 500°F direct heat. Also available in sewn seam.
