The Funk Motorsport Black Silicon High Heat Sleeve is engineered for enthusiasts and professionals who demand reliable heat protection for vital lines and wiring in high-performance, off-road, and motorsport vehicles. This premium heat protection sleeving is designed to shield fuel lines, oil feeds, wiring looms, and hydraulic hoses from the intense radiant heat generated by turbos, manifolds, and exhaust systems.
This sleeving acts as a robust thermal barrier, helping to prevent heat soak and thermal degradation of sensitive components routed near extreme heat sources. By sliding the sleeve over exposed lines and securing it, you create a protective layer that withstands temperatures up to 1000°C, reducing the risk of heat-related failures and increasing long-term reliability.
The Black Silicon High Heat Sleeve is ideal for builds where space constraints force lines and wiring close to hot engine or exhaust components. Typical applications include:
This product is particularly suited for those upgrading or maintaining vehicles exposed to demanding thermal environments, such as motorsport competitors, off-road explorers, and performance road car owners.
Manufactured from high-grade black silicon, this sleeve offers excellent thermal resistance and durability under vibration and repeated thermal cycling. It is available in multiple diameters and lengths, allowing you to select the best fit for your specific lines or harnesses. The material is resistant to most automotive fluids, supporting use in harsh engine bay conditions.
Installation is straightforward: simply measure the required length, cut the sleeve to size, and slide it over the component to be protected. Secure the ends with clamps or cable ties as appropriate. The flexible nature of the silicon makes it easy to route around bends and through tight spaces, making it suitable for both new builds and retrofits.

Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
This sleeve is ideal for fuel lines, oil feeds, wiring harnesses, brake lines, and hydraulic hoses exposed to high temperatures in the engine bay or near exhaust components.
Measure the outer diameter of the line or harness you wish to protect and select a sleeve size that provides a snug fit without excessive slack. Multiple diameters are available for a tailored solution.
Yes, it is designed for use in motorsport, off-road, expedition, and performance road vehicles where thermal protection is critical.
The black silicon construction is resistant to most common automotive fluids, supporting reliable long-term use in harsh environments. However, avoid prolonged direct contact with aggressive chemicals where possible.
No specialist tools are required. The sleeve can be cut with standard scissors and secured using clamps or cable ties.
Silicon sleeves offer flexible, durable protection and are easier to install in tight spaces, while reflective or fibreglass options may provide different thermal properties for specific applications. Choose based on your build’s layout and heat exposure.
Check dimensions, mounting points, clearance and any wiring or hose requirements against your setup before ordering.
Send us your vehicle, year, current setup and any fitting date, event, trip or deadline before ordering. We will help check fitment, product choice and timing.
