Using this Ancor heat shrink tubing is easy. First, choose the right size for your project. The tubing has a 3/8 - inch diameter and shrinks to 1/8 - inch. Slip the tubing over the object you want to cover. Then, use a heat source to heat the tubing. It will start to shrink at 257°F or 125°C. Make sure to heat it evenly to get a proper seal. When heating, be careful not to overheat as it may damage the tubing. Also, keep it away from open flames as it can be a fire hazard. After use, store the tubing in a cool, dry place. Avoid exposing it to direct sunlight for long periods as this can affect its performance. This tubing is great for protecting against salt water, oil, and acids, but if it gets dirty, you can gently wipe it with a clean, dry cloth.
