Keep your wiring, lines, and cables safe from heat. Forget about that old fire silicone sleeving (450°F max); Reflect-A-Sleeve acts as a thermal barrier capable of reflecting up to 95% of radiant heat away. It is excellent to use on your fuel lines. Keeping fuel cool helps to prevent vapor lock and also reduces fuel evaporation. The cooler air fuel mixture improves the efficiency of motor, increasing fuel mileage and performance. *Weight* there is more, a 3' length our Reflect-A-Sleeve weighs less than 6" of the old silicone covered stuff. Though it weighs much less, it offers superior heat protection. Reflect-A-Sleeve withstands 1100°F continuous of radiant heat and 500°F direct heat. Also available in a hook and loop seam click here. Custom sizes available.
