Protect The Little Things That Keep You Moving

When you’re chasing horsepower, heat comes with the territory, but it doesn’t have to destroy the little things that keep your engine running right. The PPE 3/4 Inch x 1ft Heat Sleeve is a smart and simple way to defend your wiring, vacuum lines, and fuel hoses from the kind of heat that sneaks in and causes real trouble. Whether you're driving a street-tuned build or a full-blown race setup, this sleeve gives you peace of mind where it matters most. Its flexible design makes it easy to slide over tight spots and wrap around sensitive areas that are close to exhaust components or turbo piping. With its clean, functional look and compact size, it fits right into your engine bay without getting in the way. Once it’s installed, you can stop worrying about melted insulation or brittle lines failing under pressure. It’s one of those upgrades you’ll appreciate every time the temps start to climb.

Built To Shield Critical Components From Intense Heat

The PPE 578010701 Heat Sleeve is constructed from tightly woven fiberglass coated in high-temperature silicone, giving it the durability to withstand prolonged heat exposure. It is rated for continuous temperatures up to 500 degrees Fahrenheit and can take short bursts reaching 2200 degrees. That performance makes it ideal for shielding components routed near hot engine zones like exhaust manifolds, turbo housings, or intercooler tubing. With a 3/4 inch diameter and 1-foot length, it provides precise coverage for smaller lines and wiring harnesses in performance applications. The sleeve is flexible and easy to install, allowing you to make quick heat management upgrades without disassembling major systems. Once in place, it helps preserve the integrity of fuel lines, electrical wiring, and vacuum hoses, extending their service life even under the strain of high-horsepower operation. Whether you're doing preventative maintenance or chasing performance, this sleeve delivers reliable thermal protection where it’s needed most.
