Thermal Sleeves
Thermal sleeves are essential for protecting critical wiring, hoses, and fluid lines from radiant heat and direct contact with hot surfaces. Whether you're routing fuel lines near headers, shielding sensor wiring around a turbo, or simply cleaning up an engine bay, the right sleeve prevents heat soak, chafing, and premature failure.
We stock sleeves in multiple materials and diameters to match the application. The typical lineup includes aluminized fiberglass for high radiant-heat rejection, basalt or silica sleeves for continuous-high-temperature environments, and split-loom options when you need to wrap existing harnesses without disconnecting connectors. Each type balances temperature rating, abrasion resistance, and flexibility so you can choose the best fit for your project.
- Deflects radiant heat to keep wire insulation and hose rubber within safe limits
- Helps prevent vapor lock in fuel lines and fluid boiling in brake or clutch lines
- Available in solid tube, split, and hook-and-loop closure styles for easy install
- Sold by the foot, in pre-cut lengths, or as part of complete kit solutions
