What kind of heat can this sleeve withstand?

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

Can I use this on braided stainless steel lines?

Yes, you can use this sleeve on braided stainless steel lines. However, you might notice a slight difference in fit compared to braided Kevlar lines, and you may need to order one size up if you have fittings already on the lines.

How do I determine the correct size for my application?

This spool has a 5/8 inch inside diameter. You can cut the sleeve to the exact length needed. If you're installing over lines with fittings, the material can stretch about 1/16 to 1/8 inch, which may help achieve a snug fit.

Product Details

This is the DEI Fire Sleeve, a 25-foot spool with a 5/8-inch inside diameter. It’s designed to protect vital lines and wiring from damaging heat and abrasion, especially in tight engine bays where things can get really hot. Think fuel lines, brake lines, transmission lines, and electrical wiring – this sleeve acts as a tough barrier.

It’s made from a braided glass material that’s coated with 100% iron oxide silicone rubber. This construction allows it to handle continuous heat up to 500°F and intermittent heat up to 2000°F. It’s a fireproof solution that can also be used for bundling and organizing hoses and wiring, keeping your engine bay tidy and protected during repairs or just day-to-day operation.

Because it's a universal product, you can cut it to the length you need for various applications. Just remember that if you're fitting it over lines with existing fittings, you might need to stretch the material slightly or consider ordering a size up, as it can stretch about 1/16 to 1/8 inch.
