Using these Ancor heat shrink ring terminals is easy. First, make sure the wire is clean and stripped to the right length. Insert the wire into the terminal. Then, use a heat gun to heat the heat shrink tubing. Keep the heat gun moving evenly around the tubing until the adhesive inside melts and forms a tight seal. When using the heat gun, be careful not to overheat as it may damage the terminal or the wire. Also, work in a well - ventilated area to avoid inhaling any fumes. For maintenance, store the terminals in a dry place to prevent corrosion. If you notice any signs of damage like cracks in the heat shrink tubing or corrosion on the terminal, replace it immediately.
