Mechanics and automotive enthusiasts, this DEI fire sleeve is serious protection for your critical components! The 5/8-inch diameter and 25-foot length give you plenty of material to protect multiple hoses, wires, or lines in your engine bay. Constructed from braided glass material coated with 100% silicone rubber, this stuff can handle continuous temperatures up to 500°F and intermittent bursts up to 2000°F - that's serious heat resistance. Installation is straightforward - just slide it over your brake lines, fuel lines, wiring harnesses, or any components near exhaust manifolds or other hot areas. The included 16-inch black fire tape finishes the ends professionally and prevents fraying. What's impressive is how flexible it remains even after heat exposure - no cracking or becoming brittle. I've used it to protect wiring near headers and fuel lines near turbo setups, and it's performed flawlessly. The silicone coating resists oil, fuel, and most chemicals, so it holds up well in harsh engine environments. It's also great for protecting your hands during under-hood work - no more burned knuckles on hot components. The quality is typical DEI - professional grade materials that you know will perform when it matters. Whether you're building a performance vehicle, protecting components in your daily driver, or need high-temp protection for industrial applications, this fire sleeve delivers reliable performance. Much better than makeshift solutions like header wrap or aluminum tape. Definitely worth the investment for peace of mind knowing your critical systems are protected from heat damage.
