Heavy-Duty Thermal Shielding

When you need to protect larger diameter hoses or bundles of wiring from the intense heat of an engine bay, the Design Engineering 1-1/4-inch Heat Sheath is the perfect choice. This aluminized sleeve is specifically engineered to reflect radiant heat, keeping your critical systems operating within safe temperature ranges. Measuring 3 feet in length, it provides ample coverage for cooling lines, intake hoses, or complex wiring looms that are exposed to exhaust manifold or turbocharger heat.

Why Choose Heat Sheath?

• Reflective Barrier: The aluminized outer surface reflects up to 90% of radiant heat, preventing thermal transfer.
• Insulating Core: The high-grade fiberglass inner layer provides excellent insulation against conductive heat.
• Versatile Sizing: The 1-1/4 inch ID is ideal for larger diameter hoses, ensuring a snug fit and maximum protection.
• Durable & Lightweight: Designed to withstand the harsh environment of a high-performance engine bay without degrading.

Heat soak is the enemy of performance. By insulating your intake and cooling systems, you maintain optimal fluid temperatures and prevent electrical issues that can lead to misfires or sensor failure. The Heat Sheath is easy to install and can be trimmed to fit your exact needs, making it a versatile tool for any automotive enthusiast or professional builder. Ensure your vehicle performs at its best under the most demanding conditions by using high-quality thermal management products. Shop the full range of protection solutions at GGCRACING.
