Using this Ancor heat shrink tubing is easy. First, slide the tubing over the area you want to cover. Then, use a heat source like a heat gun. Aim the heat at the tubing evenly until it shrinks to fit snugly. Make sure to keep the heat source moving to avoid overheating in one spot. When using it, always work in a well - ventilated area. Avoid using it near flammable materials. For maintenance, store the tubing in a cool, dry place. If you notice any signs of damage like cracks or breaks, don't use it and replace it with a new piece.
