Ultimate Thermal Protection for Engine Components

The DEI Heat Sheath 3/4in x 3ft is the professional-grade solution for protecting critical lines, hoses, and wiring harnesses from harsh under-hood environments. Engineered for durability, this aluminized sleeving prevents failure caused by extreme heat, chemical spills, and road grime.

Key Technical Features

  • Radiant Heat Resistance: Withstands up to 2000°F of radiant heat.
  • Direct Heat Rating: Safe for constant temperatures up to 500°F.
  • Flexible Design: Pliable material allows for tight bends around engine components.
  • Durable Construction: High-temperature glass fiber fabric bonded to a reflective aluminized outer layer.

Whether you are building a track car or restoring a classic, the DEI Heat Sheath provides a clean, professional look while ensuring your vehicle's electrical and fluid systems remain protected from heat soak. The sewn-edge design offers superior integrity compared to standard sleeves, making it ideal for high-vibration applications. Installation is simple: trim to your desired length and slide over existing lines to shield against oil, grease, and debris. Please note that this product should not be applied directly to exhaust components. For premium thermal management solutions and expert advice, trust the inventory at GGCRACING.
