Heat Sheath 1.5in ID x 50ft

The DESIGN ENGINEERING Heat Sheath 1.5in ID x 50ft is a professional-grade thermal protection sleeve designed for engine builders and performance mechanics who require effective heat management in tight engine bays. This 50-foot roll is ideal for routing fuel lines near exhaust manifolds and protecting wiring harnesses from radiant heat.

Constructed with a 1.5-inch inner diameter, the Heat Sheath accommodates fuel hoses, brake lines, and bundled wiring without compressing them, ensuring optimal flow and signal integrity. Its expandable, braided design allows for flexible routing around engine components and tight spaces where rigid tubing may not fit. The formulation effectively reflects radiant heat while maintaining flexibility at extreme temperatures.

This product is particularly beneficial for turbocharged and supercharged builds, EFI conversions, and vintage restorations. The 50-foot length provides ample coverage for full-vehicle fuel system protection and extensive wiring harness wrapping in custom engine conversions.
