SLIT Cool-Tube is designed to protect wiring, fuel lines, brake lines and other areas from extreme heat (up to 500°F) Manufactured from convoluted Nylon 6 tubing - no plastic - and covered with an aluminized fibreglass fabric, Cool Tube combines flexibility with maximum thermal protection.

The aluminised covering provides heat reflectivity, reducing temperatures an average of 43%. Cool Tube resists abrasion, chemicals and condensation. The slit version eliminates the necessity of disconnecting wire or lines.

Cool Tube is available in 1/2" and 3/4" diameters and in 3 ft and 15 ft lengths

Excellent product — exactly as described.

Used this on a JCB 3CX turbo downpipe. Fits perfectly, holds up very well to heat cycles. Much better than the fibreglass wrap I used previously — no itching, easier to handle. Will definitely be ordering again.

Great value, fast delivery.

Good quality wrap for the price. Arrived next day which was great. The 50mm width covered my headers nicely with a bit of overlap. Holds up well after a few heat cycles.

Decent product, application tricky without soaking first.

Wrap itself is good quality but I'd strongly advise soaking in water for 10–15 mins before wrapping — it makes it much more pliable and easier to apply. Didn't do this first time and it was frustrating. Product is fine though, no complaints.
