Big Protection For The Hottest Parts In Your Bay

When the heat is cranked up under the hood, even your biggest components need proper protection. The PPE 2.5 Inch x 1ft Heat Sleeve is the perfect solution when you’ve got thick coolant lines, large harnesses, or other bulky parts running dangerously close to turbo housings, intercooler piping, or exhaust systems. It’s short enough to install exactly where you need it most, but large enough to wrap around those wider diameter parts without a fight. The high-temp silicone coating looks clean and adds durability, while the fiberglass core does the heavy lifting when it comes to keeping heat out. This sleeve makes a smart addition to any build, especially when you’re trying to protect your investment from the kind of heat that creeps up and causes failures. It slides on easily, stays flexible, and takes the guesswork out of heat protection. If you’re running high horsepower, high temps, or both, this is the kind of insurance your engine bay deserves.

Designed To Fit Large Components With Serious Heat Exposure

The PPE 578012501 Heat Sleeve offers targeted thermal protection for oversized components commonly found in high-output engine setups. Built with a 2.5-inch internal diameter and a 1-foot length, it is ideal for protecting large-diameter coolant hoses, thick wiring bundles, or intake tubing routed through high-temperature areas. The sleeve is constructed from tightly woven fiberglass and coated in high-temperature silicone, allowing it to handle continuous temperatures up to 500 degrees Fahrenheit and withstand brief spikes up to 2200 degrees. Its flexible design ensures easy installation, even when working around tight corners or complex routing paths. This makes it especially useful in forced induction builds or vehicles with limited engine bay space. By reducing direct heat exposure, the sleeve helps preserve component integrity and minimize performance losses from heat soak or premature wear. It is a simple, durable, and effective solution for critical heat management needs.
