Uxcell 33-Foot X 4mm High Temp Silicone Fiberglass Insulation Sleeve – Black, Heat Shield Tubing For Wires, Motors, And Engines

About This Product

If you've got wires running near heat sources – like in an engine bay, around a motor, or near exhaust – this uxcell insulation sleeve is a smart investment.

It's 33 feet long with an inner diameter of 4mm, and it's made from alkali-free fiberglass coated with silicone resin.
That gives it a working temperature range from -60°C to +200°C, so it handles serious heat without breaking down.

It's also rated for 1200V and has a VW-1 flame resistance rating, so it's safe for high-voltage applications.

The sleeve keeps your wires neat, organized, and protected from heat damage.

Use it for plug wires, fuel lines, decorative lighting, motors, or anyplace where you need extra insulation.

One important note, though: this sleeve is an insulator, so it'll trap heat inside the wire if the wire is already overheating.
That could cause the wire's own insulation to melt.

So make sure your wire gauge is appropriate for the load you're running.

If it's already getting hot, you need a bigger wire, not just a sleeve.

But for protecting wires from external heat, this stuff works great and it's easy to cut to length with scissors or a knife.
