Thermo Flex Heat Shield 1-1/2in X 36in

The THERMO-TEC Thermo Flex Heat Shield 1-1/2 inch by 36 inch is an aluminized fiberglass hose and wire sleeve designed to protect sensitive components from radiant engine heat in high-temperature environments. This thermal barrier solution is engineered for applications where engine compartment temperatures demand reliable heat dissipation and component isolation—from motorsports builds to industrial equipment installations.

The 1-1/2 inch inner diameter accommodates hoses, fuel lines, electrical harnesses, and brake lines, while the 36-inch length provides flexible coverage for runs requiring extended protection. Aluminized fiberglass construction reflects radiant heat away from protected components, maintaining lower operating temperatures and extending the service life of fuel systems, wiring insulation, and other heat-sensitive materials. The silver metallic finish reflects thermal radiation while offering visual clarity during engine bay inspections and builds.

This heat shield is essential for custom engine builds, high-performance vehicles, and applications where component proximity to exhaust headers or turbochargers creates genuine thermal risk. Fabricators and engine builders rely on sleeving solutions like this to prevent fuel line degradation, prevent electrical harness damage, and protect brake fluid integrity in tight engine bays where thermal management is critical.

The THERMO-TEC brand is recognized in the automotive and motorsports community for heat management products that deliver measurable thermal protection in demanding environments. This single sleeve offers a cost-effective thermal barrier suitable for point-source protection or as part of a comprehensive heat management strategy in engine compartments where component safety is non-negotiable.
