That kind of heat isn't just uncomfortable, it can slowly damage the important stuff like hoses, wires, and fuel lines. The PPE 3.5-inch x 1-foot Heat Sleeve is built to take the punishment so your components don’t have to. It’s a simple solution that can save you from bigger headaches down the road, especially if you're running a turbo setup or high-performance build. With its rugged fiberglass core and silicone outer layer, it deflects heat before it ever touches your lines. Whether you're carving through backroads, trailering to track days, or just keeping your daily driver in top shape, this sleeve adds a smart layer of protection right where you need it. It's the kind of upgrade you can feel good about because it works, it lasts, and it makes a real difference. Engineered To Withstand What Your Build Throws At It The PPE 578013501 Heat Sleeve is a performance-grade barrier designed for serious thermal protection. It’s crafted from woven fiberglass wrapped in high-temperature silicone, giving it the ability to withstand a steady 500°F and endure short bursts up to 2200°F. That makes it an excellent fit for shielding everything from fuel and coolant lines to vacuum hoses and sensitive electrical wiring. With its 3.5-inch diameter, this sleeve is made for larger components that tend to run close to turbo housings, intercooler piping, or exhaust sections. At 1 foot in length, it offers a flexible coverage option that can be cut or overlapped depending on your application. The installation is straightforward—just slip it over the section that needs protection, and you're good to go. This kind of heat management is crucial in high-horsepower or forced induction builds where excessive heat can compromise performance and reliability.
