1-1/2in x 12ft Thermo Sleeve

The 1-1/2in x 12ft Thermo Sleeve by THERMO-TEC is a professional-grade hose and wire management solution designed to protect sensitive engine components from extreme heat exposure. This aluminized fiberglass sleeve is engineered for automotive, powersports, and industrial applications where thermal protection is critical. Whether you're routing fuel lines, brake hoses, or electrical wiring near high-temperature zones, this sleeve prevents degradation, maintains system integrity, and extends component lifespan in demanding environments.

Constructed from aluminized fiberglass material, the 1-1/2in x 12ft Thermo Sleeve provides exceptional thermal reflection and insulation without adding significant weight at just 0.8 lbs. The aluminized exterior surface reflects radiant heat away from protected lines, while the fiberglass core maintains structural integrity under continuous thermal cycling. The 1-1/2 inch inner diameter accommodates standard hoses and wire bundles, and the 12-foot length provides substantial coverage for complex engine bays, exhaust systems, or custom fabrication projects. Installation is straightforward—simply wrap or slip the sleeve over target components and secure with clamps or fasteners as needed.

Engine builders, hot rodders, and motorsports enthusiasts rely on thermal sleeves to protect fuel systems, coolant lines, and wiring harnesses in high-performance applications where underhood temperatures exceed standard tolerances. The 1-1/2in x 12ft configuration is ideal for single-hose protection or bundled wire applications in mid-sized engine compartments. This product is compatible with both gasoline and diesel powerplants and performs reliably in race cars, trucks, marine engines, and industrial equipment. For maximum thermal protection and professional-level component preservation, THERMO-TEC's aluminized fiberglass sleeve is an essential upgrade.
