Pacific Performance Engineering Heat Sleeves

Pacific Performance Engineering heat sleeves are designed to protect sensitive under-hood components from the extreme temperatures generated by high-horsepower diesel and performance applications. Constructed from silicone-coated woven fiberglass, these durable heat sleeves provide reliable insulation for vacuum and boost lines, fuel lines, electrical wiring, coolant hoses, and other vulnerable components routed near intercooler tubing, exhaust pipes, turbo housings, and hot engine surfaces. Capable of withstanding continuous temperatures up to 500 degrees F and brief heat exposure up to 2,200 degrees F, these heat sleeves help prevent heat-related damage, improve component longevity, and support cleaner, more dependable engine bay installations. Available in multiple inside diameters and lengths, the PPE heat sleeves provide a flexible solution for custom builds, repairs, and performance upgrades.
