What kind of heat can this Fire Sleeve withstand?

This DEI Fire Sleeve is rated to handle continuous heat up to 500°F. It can also withstand intermittent heat exposure up to 2000°F, making it suitable for demanding engine bay environments.

Can I use this on lines that already have fittings attached?

The material has some stretch, allowing for about 1/16 to 1/8 inch expansion. However, if your lines have bulky fittings, you may need to order a size larger to ensure an easy installation.

What is the best way to install this sleeve on a hose?

Simply slide the sleeve over the hose or wire you wish to protect. For a tighter fit or to prevent fraying, you can use DEI's Fire Tape (sold separately) to secure the ends.

Product Details

When you're working on your engine, especially if you've got a high-performance setup or you're dealing with tight spaces, protecting vital lines and wiring from heat is a big concern. This DEI Fire Sleeve is designed to do just that, acting as a tough barrier against radiant and direct heat. It's made from a braided glass material that's coated with silicone rubber, giving it the ability to handle serious temperatures.

This sleeve is great for wrapping around fuel lines, brake lines, transmission lines, or even electrical wiring that's close to hot engine components. It can handle continuous heat up to 500°F and even intermittent bursts up to 2000°F, so it offers solid protection in most underhood situations. The 1-inch inside diameter is a popular size for many common hoses and lines, and you get a full 25 feet on the spool, which is usually enough for multiple applications or longer runs. It's also useful for bundling wires together neatly.

Keep in mind that while this material has some stretch, if you have lines with fittings already attached, you might need to order a size up to get it over them. It's a well-built solution for preventing heat damage and abrasion to critical components.
