1 1/2in x 3' Thermo Sleeve

The 1 1/2in x 3' Thermo Sleeve from THERMO-TEC is a premium hose and wire protection solution engineered for demanding thermal environments where standard sleeves fall short. Designed for engine compartments, exhaust systems, and high-temperature industrial applications, this aluminized fiberglass sleeve shields vulnerable hoses and wiring harnesses from radiant heat, preventing degradation and potential system failure. Whether you're protecting fuel lines, coolant hoses, or electrical conduits in a performance engine bay or industrial facility, this sleeve offers the durability and heat resistance professionals demand.

Constructed from aluminized fiberglass, the 1 1/2in x 3' Thermo Sleeve combines lightweight construction with exceptional thermal protection characteristics. The aluminized exterior reflects radiant heat away from protected components, while the fiberglass core provides insulation and structural integrity without adding significant weight—just 0.22 lbs for the complete 3-foot length. The 1 1/2-inch inner diameter accommodates standard hoses and wire bundles, and the 3-foot length provides flexibility for custom routing and installation across multiple components. The silver finish ensures visibility during installation and inspection, while remaining resistant to oil, fuel, and common engine bay contaminants.

This sleeve is ideal for automotive enthusiasts, mechanics, and industrial technicians protecting critical hoses in modified or stock engine builds. Installation is straightforward—simply slip the sleeve over the target hose or bundle and secure with appropriate clamps or ties at intervals. The aluminized fiberglass construction resists fraying and maintains its protective properties through years of thermal cycling, making it a cost-effective solution for extending component lifespan and preventing costly heat-related failures in high-performance and industrial environments.
