Using this heat shrink tubing is easy. First, choose the right size for your project. Slide the tubing over the area you want to cover. Then, use a heat source like a heat gun. Keep the heat source moving evenly around the tubing. The tubing will start to shrink when it reaches 257°F (125°C). It'll shrink to 1/3 of its original size. Make sure to keep the heat source at a safe distance to avoid overheating. This tubing can handle temperatures from -40°C to 110°C, so it's suitable for many environments. When not in use, store it in a cool, dry place. The adhesive lining provides a good seal against salt water, oil, acids, and sunlight, but try to avoid long - term exposure to harsh chemicals. Also, be careful as it's stronger than PVC but can still be damaged if handled roughly.
