How to use

Cut the heat shrink tube to the required length and slide it over the cable or joint to be insulated. Apply heat evenly using a heat gun, hot air tool or suitable heating source until the tube contracts and the internal adhesive flows, creating a tight seal around the cable. Allow the sleeve to cool so the adhesive sets and the sleeve adheres securely.

Recommendations

For best results, use a controlled hot air gun and apply heat uniformly to avoid overheating. Ensure cables are clean and dry before application. Select an initial sleeve diameter appropriate for the unshrunk cable size so that, after shrinkage, it fully covers the joint without excessive stress.
