Heat Shroud AN Line 12AN x 10ft

The Heat Shroud AN Line 12AN x 10ft from Design Engineering is purpose-built thermal protection for high-performance fuel and hydraulic line systems in modified vehicles. Whether you're running a turbocharged engine bay, managing heat-sensitive fuel injectors, or protecting braided stainless steel AN lines near exhaust manifolds, this heat shroud sleeve delivers critical insulation where factory routing falls short. Professional builders and enthusiasts rely on this product to prevent fuel boiling, reduce line degradation, and maintain system integrity in extreme underhood environments.

Constructed from aluminized fiberglass fabric, the Heat Shroud AN Line combines a reflective outer surface that bounces radiant heat away from fuel and fluid lines with a flexible, lightweight sleeve architecture that fits standard 12AN hose without bulk or installation complexity. The 10-foot length accommodates full engine bay runs, custom manifold routing, or turbo feed/return lines without requiring multiple sleeves or splice points. The silver finish provides superior radiant heat rejection compared to uncoated fiberglass, critical when lines run parallel to headers or intercooler piping in tightly packed modern engine bays where ambient underhood temperatures exceed 300°F.

This sleeve is essential for fuel system modifications, turbocharged builds, supercharger installations, and any custom hydraulic or coolant line routing where proximity to heat sources is unavoidable. It pairs seamlessly with AN-spec braided hose and works in conjunction with fuel regulators, boost control systems, and remote-mounted filtration to protect against thermal degradation and vapor lock. At 0.9 lbs for the complete 10-foot run, it adds minimal weight while providing the thermal barrier that separates reliable performance from fuel system failures under track or high-boost conditions.
