Why choose it

The 2:1 shrink ratio provides a snug fit over irregular shapes, while the polyolefin material offers excellent electrical insulation and mechanical protection. The dispenser box allows for easy cutting to the desired length without waste.

Ideal use cases

• Insulating electrical splices and terminations
• Bundling and organising cables in control panels
• Providing strain relief for connectors and wire ends
• Protecting against corrosion and abrasion in harsh environments

Good to know

For best results, use a heat gun set to at least 90 °C and apply heat evenly until the tubing conforms tightly to the substrate.
