Exoracing Silicone Fibreglass High Temperature Heat Sleeve 0.5m

Description

Why Use Silicone Fibreglass Heat Sleeve?

Extreme engine bay temperatures can make hoses go brittle, dry out wiring insulation and shorten the life of oil, coolant, brake and fuel lines. This is especially common around turbochargers, exhaust manifolds, downpipes and tight engine bays where there is very little airflow.

By sliding a silicone fibreglass heat sleeve over the vulnerable part, you add a dedicated insulation layer between the heat source and the component you need to protect. It helps reduce heat exposure, protects against rubbing, and gives the engine bay a tidy motorsport-style finish.

This sleeve is ideal for protecting turbo oil and water lines, fuel hoses, brake lines, coolant hoses, vacuum lines, battery cable, sensor wiring and wiring looms. If the main heat source is the turbo itself, pair the sleeve with an Exoracing turbo blanket to reduce radiant heat at the source as well as protecting the nearby lines.

The sleeve has a useful amount of stretch, so it can be pushed over many installed fittings and shaped around common engine bay routes. If you need to protect a hose or loom that cannot be disconnected, use our Exoracing Velcro heat sleeve instead, as it wraps around parts in place.

Silicone Fibreglass Heat Sleeve Installation Guide

1. Measure the outside diameter of the hose, cable, line or loom you want to protect.
2. Choose the closest sleeve ID above that measurement. Go one size larger for tight bends, bulky fittings or awkward routing.
3. Measure the length you want to cover and cut the sleeve with sharp scissors.
4. Slide the heat sleeve over the hose, line or wiring.
5. Position it so the most heat-exposed section is fully covered.
6. Secure the ends with the supplied heat shrink tags, wire, or Exoracing stainless steel cable ties if the sleeve needs extra retention.
7. Check that the sleeve is not touching belts, pulleys, sharp edges or moving parts.

Frequently Asked Questions

What size heat sleeve do I need?

Measure the outside diameter of the hose, cable or loom and choose the closest sleeve ID above that measurement. For example, if the hose measures around 14mm OD, choose 15mm ID unless the route is tight, in which case 20mm may be easier to fit. Use our heat sleeve size chart if you are unsure.

Can this sleeve go over fittings?

In many cases, yes. Silicone fibreglass heat sleeve has some stretch, so it can be pushed over many hose ends and fittings. If the fitting is too large or the part cannot be removed, use a Velcro heat sleeve instead.

Is this better than a reflective sleeve?

It depends on the job. Silicone fibreglass sleeve is a strong choice for direct insulation and abrasion protection around hoses, wiring and lines. Reflective sewn or Velcro sleeve is better when the main issue is radiant heat, and you want a gold or silver heat-reflective outer surface.

Can I cut it to length?

Yes. Cut the sleeve with sharp scissors, then secure the ends with the supplied heat shrink tags, wire or stainless cable ties if required.

Does it include a warranty?

Yes. This product includes the Exoracing lifetime warranty.

Notes

• Choose the next size up for tight bends, bulky fittings or awkward routing.
• Keep the sleeve clear of belts, pulleys, sharp edges and moving parts.
• For direct exhaust pipe protection, use an exhaust wrap rather than a sleeve.
• If you are not sure which heat-management product you need, read our heat shield vs exhaust wrap vs heat tape guide.
