Using these Ancor heat shrink ring terminals is easy. First, make sure the wire you're using fits the 12 - 10 5/16' size. Slide the terminal onto the wire. Then, use a heat source like a heat gun to heat the terminal. As you heat it, the adhesive inside the heat shrink tubing will activate and form a tight, waterproof seal around the wire. Be careful not to overheat the terminal as it might damage the adhesive or the terminal itself. When it comes to maintenance, keep them in a dry place to prevent corrosion. Check the terminals regularly for any signs of wear or damage, and replace them if needed.
