Why use our Silicone Fibreglass heat sleeve? 

Extreme temperatures in the engine bay of a performance vehicle are common, and they can lead to catastrophic failure of critical components. 

By using our Silicone fibreglass heat sleeve, you can cover lines, hoses and cables, protecting them against harsh temperatures. 

Do you have a turbocharger on your car? If so, your oil and water lines will be exposed to massive heat cycles every time you use the vehicle, eventually making your hoses brittle and fail. 

Even naturally asperated vehicles, especially highly tuned cars, will experience massive temperatures in the engine bay. A heat sleeve will benefit any brake line, water hose, or any wiring exposed to heat, extending the lifespan of these components and helping to avoid failure. 

Our silicone heat sleeve is made from a heat-treated, braided fibreglass coated with high-grade silicone rubber. 

The silicone/fibreglass heat sleeve is designed to withstand extreme temperatures. It is self-extinguishing, offers great short-term flame protection, and has excellent thermal insulation properties.

Another great benefit of our heat sleeve is its natural amount of stretch, which ensures a snug fit on any size hose while still allowing you to push over a fitting already attached to a hose.

Protecting vital components against heat is one of many jobs the silicone heat sleeve is suitable for. It's common that over time, due to movement, lines and hoses can get worn down from rubbing against chassis or other components. By adding a heat sleeve, you are helping to stop this happening, which could cause a leak or, worst case, engine failure! 

Our heat sleeve is supplied in black to ensure it will leave a tidy look in any vehicle. It is sold in lengths of 0.5m but can be provided in one uncut length up to 20m. When you recieve your sleeve, you can cut it down to size with just a pair of sharp scissors! 

Ultimately, if you have lines, hoses, or looms that need protection from extreme temperatures, our silicone fire sleeve is by far the best solution for automotive or industrial applications!

Silicone Fibreglass Heat Sleeve Installation Guide:

Installing our Silicone Fibreglass Heat Sleeve couldn't be easier! Just follow these few steps below:

  1. Measure how much of your line/hose you want to cover with the heat sleeve.
  2. Cut the heat sleeve down to the correct length using a pair of sharp scissors.
  3. Feed the heat sleeve over the line/hose
  4. If the sleeve is tight enough, no securing will be needed. 
  5. If you need to secure the heat sleeve, attach a metal cable tie, heat shrink or wire at either end of the heat sleeve.
