The DEI Heat Sheath model 10403 offers superior protection for lines, hoses, and wires exposed to extreme heat and harsh environments. Crafted from a high-temperature fabric bonded to an aluminized layer, this sleeving effectively reflects heat and shields against chemical spills, oil, dirt, grease, and road grime. Its innovative design allows it to slide easily over existing components, providing a secure and durable barrier that prevents heat-related failures. Ideal for automotive applications, the Heat Sheath is fireproof and can withstand direct heat up to 500°F, withstanding radiant heat up to 2000°F, making it suitable for demanding conditions. Its pliability ensures it can be bent tightly around curves and complex routing paths without compromising protection, and it can be trimmed to meet specific length requirements, offering flexibility for custom installations. Please note that this product is not recommended for direct application on exhaust components and is available in various diameters up to 50 feet in length, with custom options available upon request. Proper handling and installation will extend the lifespan of your electrical and fluid systems, reducing maintenance costs and preventing failures caused by heat and abrasion. The Heat Sheath is a reliable choice for automotive, industrial, and racing environments where high heat resistance and durability are critical. The product complies with Prop 65 regulations and is designed to meet the stringent demands of professional applications, ensuring safety and performance. Each package includes one 36-inch length of sleeving with a 3/4-inch inside diameter, ready for installation in a variety of automotive or industrial settings.
