1/2in x 12' Thermo Sleeve

The THERMO-TEC 1/2in x 12' Thermo Sleeve is a high-temperature hose and wire protection system designed for demanding engine compartment and exhaust system applications. This product is ideal for engine builders, automotive technicians, drag racing teams, and hot rod fabricators who require reliable thermal protection for sensitive hoses and wiring.

Constructed from aluminized fiberglass, this 12-foot sleeve reflects radiant heat while protecting hoses, wiring, and fuel lines from extreme temperatures. The 1/2-inch inner diameter accommodates standard hose and wire bundles, while the flexible material allows for easy routing around engine components. The sleeve maintains its integrity at sustained high temperatures and resists exposure to oils, coolants, and fuels.

With its extended 12-foot length, the Thermo Sleeve supports complete routing from the engine block to the firewall or fuel tank, reducing the need for multiple sleeves. This makes it an essential tool for anyone working in motorsports or high-performance automotive environments where temperature management is critical for component longevity and safety.
