🧩 Instructions for Use

1. Begin by wrapping the tubing around the cable wire that requires insulation.
2. Using a heat gun, evenly apply heat to the tubing until it shrinks snugly around the wire.
3. Allow the tubing to cool completely before handling to ensure a secure seal.

🔒 Please ensure that the temperature of your heat gun reaches at least 212℉ (100℃) for optimal results—this allows the adhesive inside the tubing to soften and create an effective seal.
