The DEI Heat Sheath, part number dei10420, offers an essential solution for protecting lines, hoses, and wires from extreme heat, abrasions, and chemical spills. Designed to slide easily over cables and hoses, this high-temperature fabric sleeve is bonded with a reflective aluminized material that effectively deflects heat, ensuring reliability in demanding environments. Its construction allows it to withstand direct heat up to 500°F and radiant heat up to 2000°F, making it suitable for a wide range of automotive and industrial applications. The flexible design ensures ease of installation and the ability to bend tightly around curves without compromising protection. Ideal for use in engine bays, exhaust systems, or any situation where heat resistance is critical, the Heat Sheath provides a durable barrier against dirt, grease, road grime, and chemical exposure, maintaining the integrity of your components. The product can be trimmed to the desired length, offering customization for various installation needs. Available in lengths up to 50 feet in different diameters, other sizes can be special ordered for specific applications. However, custom-cut patterns and lengths are non-returnable. Note that this sleeving should not be applied directly to exhaust components, but it excels in protecting wiring and tubing from heat and physical damage in automotive and industrial settings.
