What this tubing is and who it suits

This black polyolefin heat-shrink tubing comes in a five-metre length with a two-millimetre inner diameter and a 2:1 shrink ratio. It is supplied new and rated for 600 V, making it suitable for insulating and protecting wires in automotive, stereo and earphone applications. The operating temperature range spans from minus 55 °C to plus 105 °C.

How it fits into a wiring job

The tubing slides over a cable or connector before termination and then shrinks when heated to at least 80 °C, reaching full recovery at 105 °C. Its cross-section reduces by fifty percent or more, gripping the wire tightly and sealing out moisture and abrasion. The thin wall keeps the assembly flexible and adds minimal bulk to the harness.

Heat, noise and power in use

Shrinkage begins at 80 °C and completes at 105 °C, so a standard heat gun or lighter provides enough energy without overheating surrounding parts. The material is passive once cooled, drawing no power and producing no noise during operation. It remains stable across the full minus 55 °C to plus 105 °C range.

Questions about this item

At what temperature does the 2:1 shrink ratio fully take hold?

The tubing begins shrinking at 80 °C and completes its full 2:1 contraction at 105 °C.

Will the 105 °C upper temperature limit handle continuous engine-bay heat?

The material is rated for sustained use from –55 °C up to 105 °C, so it tolerates typical under-hood temperatures.

Does the 600 V rating mean I can use this on mains-voltage wiring?

Yes, the tubing is rated for 600 V ambient, making it suitable for mains-voltage insulation when applied correctly.
