Product Details

When you're working around the engine bay, especially on a hot running vehicle, keeping sensitive wires, cables, and hoses protected from extreme heat is a big deal. DEI's Cool Tube Extreme is a well-built solution designed to handle those tough conditions. It's made from a special composite material that can reflect continuous heat up to 750°F, giving you solid protection against the intense temperatures found under the hood.

What's really handy about this Cool Tube is that you don't have to disconnect anything to install it. It's designed to be slit lengthwise, so you can just wrap it around your existing cables or hoses and secure it. The spiral wire reinforcement inside makes it flexible enough to bend around tight corners without kinking, and the tough, easy-to-clean finish looks professional. Plus, you get a 9-foot length, so you can trim it down to exactly what you need for the job.

Just remember, this is for protecting components from heat, not for direct contact with exhaust parts. It's a smart way to add a layer of defense to your wiring and fluid lines.
