Product Details

DEI is known for making parts that help manage heat in your vehicle, and this Fire Sleeve is a prime example. If you're working on protecting fuel lines, brake lines, transmission lines, or even electrical wiring from damaging heat and abrasion, this is a solid option. It's built to handle some serious temperatures, making it useful for keeping critical components safe under the hood.

This sleeve is constructed from a high-temperature resistant braided glass material that's coated with 100% iron oxide silicone rubber. This combination gives it the ability to insulate against direct heat up to 500°F continuously, and it can even handle intermittent heat up to 2000°F. It's also useful for bundling and protecting various hoses and wiring, which can help keep your engine bay tidy and prevent damage.

You get a full 100-foot spool here, so you'll have plenty to work with for multiple projects or longer runs. Remember that if you have fittings already attached to your lines, you might need to order a size up, as the material can stretch a small amount, typically between 1/16 and 1/8 of an inch.
