Wrap Your Build With Confidence From Start To Finish

If you’re building something serious under the hood, the last thing you want is heat taking out your hard work. The PPE 3/4 Inch x 50ft Heat Sleeve gives you the freedom to protect everything at once, no piecing together short scraps or leaving wires exposed. With a full 50-foot roll, you’ve got more than enough length to wrap multiple vacuum lines, wiring harnesses, fuel lines, and coolant hoses. It’s ideal for high-horsepower applications where engine bay temps can climb fast, especially near turbos, intercoolers, and exhaust pipes. The sleeve's flexible silicone-coated fiberglass design is easy to work with and fits tight spots without a struggle. You’ll be able to route and protect everything cleanly, while also giving your bay a more finished, professional look. Whether you're rewiring, rebuilding, or reinforcing, this sleeve brings real protection and peace of mind to your project.

Extended Length Protection Built For Demanding Heat Zones

The PPE 578010765 Heat Sleeve is engineered to handle the extreme thermal environment of performance engine bays. Constructed from woven fiberglass with a high-temperature silicone coating, it delivers long-term heat shielding for components exposed to continuous temperatures of 500 degrees Fahrenheit and momentary spikes up to 2200 degrees. Its 3/4 inch internal diameter is optimized for protecting smaller lines and cables such as boost reference hoses, electrical wiring, or transmission cooler lines. At 50 feet in length, this sleeve offers extensive coverage, making it ideal for full vehicle installs or large custom setups. It excels in high-stress areas where components pass close to hot engine parts like turbo housings or exhaust manifolds. The sleeve acts as a barrier that not only deflects radiant heat but also helps preserve the material integrity of whatever it wraps. Easy to cut and position, it provides versatile thermal control without requiring major disassembly. This is a professional-grade solution for anyone needing consistent and scalable heat protection.
