How to use

Cut a suitable length of heat shrink tube and slide it over the cable or connection to be insulated. Apply heat evenly using a heat gun, lighter or other controlled heat source until the tube shrinks uniformly and conforms tightly to the cable. Allow the sleeve to cool and inspect the fit to ensure a complete seal and proper insulation.

Recommendations

Use controlled heat sources and heat evenly to avoid overheating. Choose a tube diameter that provides adequate shrinkage over the cable before heating. For electrical safety, ensure connections are insulated and secured before use and follow local electrical codes.
