Silicone Fiberglass Sleeve Heat Shield Wire Protective High Temperature Electrical Insulation Self-extinguishing Black (5/16"-9ft) - desertcart.com

Review: Best High Heat Wiring Sleeve - This stuff is perfect for what I needed. I was running reverse switch wire through my engine compartment, into the cab of my car for a manual swap. The engine puts off some serious heat where I need to route the wires. This sleeve is the real deal. Will come back to this stuff for wire bundles small and large!
Review: Very Good Quality - I bought it for my waffle maker that wasn’t heating up. I opened it and found that the problem was the cable covering was burned, which caused the issue. Fortunately, I was able to find this heat resistant cable protector of very good quality. Good product.
