Funk Motorsport Black Silicon High Heat Sleeve – Heat Protection Sleeving for Extreme Temperatures

High-Temperature Protection for Critical Engine Bay Components

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.

What the Black Silicon High Heat Sleeve Does

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.

Where This Heat Protection Sleeving Is Most Useful

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:

• Protecting fuel and oil lines adjacent to turbochargers or downpipes
• Shielding wiring harnesses in engine bays of track, off-road, or expedition vehicles
• Safeguarding brake lines and hydraulic hoses during high-load or endurance driving
• Supporting custom installations where heat exposure is unavoidable

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.

Key Benefits of Funk Motorsport Heat Protection Sleeving

• Withstands continuous temperatures up to 1000°C (as verified by Funk Motorsport)
• Flexible silicon construction for easy routing and installation
• Available in a range of diameters and lengths to suit most automotive and motorsport applications
• Helps prevent heat-induced failures and extends component lifespan
• Can be cut to length for a tailored fit
• Suitable for both professional workshops and DIY installations

Construction and Sizing Details

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 and Usage Guidance

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.

Frequently Asked Questions

Which components are best protected by this sleeving?

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.

How do I choose the correct diameter for my application?

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.

Can the Black Silicon High Heat Sleeve be used in both road and competition vehicles?

Yes, it is designed for use in motorsport, off-road, expedition, and performance road vehicles where thermal protection is critical.

Is the sleeve resistant to automotive fluids and oils?

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.

Do I need special tools for installation?

No specialist tools are required. The sleeve can be cut with standard scissors and secured using clamps or cable ties.

How does this product differ from reflective or fibreglass heat sleeves?

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.
