Tubular Aluminum Heat Reflective Sleeve: Advanced Thermal Protection for Automotive Applications

Engineered to safeguard critical automotive components from extreme heat, the Tubular Aluminum Heat Reflective Sleeve is an essential solution for thermal management in high-temperature environments. Designed specifically for automotive wire harnesses, hoses, and cables, this innovative sleeve creates a reliable thermal buffer by reflecting radiant heat away from sensitive electronics, fluid lines, and electrical systems.

Core Structure & Technology:
Crafted through a precision lamination process, the sleeve combines an aluminized metallic outer layer with a robust inner layer of tightly braided fiberglass insulation. The outer aluminized shield acts as a highly efficient heat reflector, deflecting up to 90% of radiant heat, while the fiberglass core provides exceptional thermal resistance and mechanical durability. This dual-layer system ensures optimal protection against temperatures exceeding 500°C (932°F), preventing heat-induced degradation, melting, or insulation failure.

Key Advantages:

Radiant Heat Reflection: Aluminum coating redirects thermal energy, maintaining lower surface temperatures for protected components.
Abrasion Resistance: Dense fiberglass braid shields against friction, vibration, and mechanical wear.
Flexible Installation: Lightweight, tubular design allows easy slip-on application without disassembling existing systems.
Chemical & Moisture Resilience: Withstands exposure to oils, fuels, and harsh automotive fluids.

Ideal Applications:

Engine Bay Wiring Harnesses: Protects ECU connections, sensors, and ignition systems from exhaust manifold heat.
Fuel Lines & Brake Hoses: Prevents vapor lock and fluid line degradation near turbochargers or catalytic converters.
EV Battery Cabling: Manages thermal loads in hybrid/electric vehicle high-voltage systems.

Performance Validation:
Tested to meet SAE, ISO, and OEM automotive standards, this heat sleeve maintains flexibility across a -65°C to +500°C (-85°F to +932°F) range. Its non-conductive fiberglass core ensures electrical safety, while the crush-resistant structure preserves integrity under hood stresses.

Upgrade your thermal management strategy with a solution that combines aerospace-grade materials with automotive-engineered reliability. The Tubular Aluminum Heat Reflective Sleeve delivers unmatched protection, extending component lifespan while reducing warranty claims and downtime.
