How to use
Slide the heat-shrinkable tube over the wire joint, terminal or connector so the area to be insulated is fully covered. Apply heat evenly (for example with a heat gun) until the tube shrinks and conforms to the components; the specified shrinkage temperature is 90°C. Allow the sleeve to cool and inspect the seal and fit to ensure complete coverage and mechanical protection.
Usage recommendations
For best results, use a regulated heat gun and keep the nozzle moving to avoid overheating the tube or underlying components. Select the tube so the initial diameter is sufficient to fit over connectors before shrinking; the TK-4.5R-K is intended for applications requiring a 4.5 mm nominal diameter and halogen-free material.
