Heat Sleeve 1/2in x 3' Silver

The Heat Sleeve 1/2in x 3' Silver from THERMO-TEC is an essential thermal management accessory designed for engine builders, performance mechanics, and serious DIY enthusiasts. This product is crucial for controlling underhood temperatures, which directly impacts the reliability and longevity of various vehicle components. It effectively protects wiring harnesses, fuel lines, and brake lines from extreme radiant heat sources.

Constructed with THERMO-TEC's proven thermal technology, the Heat Sleeve features a silver reflective exterior that bounces radiant heat away from vulnerable components. Its flexible design allows for easy routing around tight engine bay spaces. The sleeve has a 1/2-inch diameter opening, accommodating hoses and lines of that nominal size, and its 3-foot length provides ample coverage for most applications.

This heat sleeve is particularly beneficial for vehicles experiencing high-performance modifications, turbo installations, or aggressive engine tuning. It performs best when protecting fuel lines near exhaust manifolds and coolant hoses routed past turbochargers. The durable aluminized outer surface withstands oil residue and vibration, while the internal insulating material resists degradation from repeated thermal cycling.
