Ancor 321625 Heat Shrink Ring Terminal, #8 3/8, 25 pieces. These heat shrink connectors have a heat-activated adhesive in the tubing sleeve. When heated, they create a watertight seal, offering excellent vibration and strain relief. The package contains items with dimensions: height 0.880 inches, width 2.690 inches, length/depth 4.380 inches, and each weighs 4.000 ounces.

Using these Ancor heat shrink ring terminals is easy. First, slide the terminal onto the wire you want to connect. Then, use a heat source like a heat gun to heat the terminal. As you heat it, the adhesive inside the tubing will melt and form a strong, watertight seal around the wire. Make sure to heat evenly to ensure a good connection. When using the heat gun, keep it at a safe distance to avoid overheating or damaging the terminal. After installation, there's not much maintenance required. Just check occasionally to make sure the seal is still intact, especially if the terminals are in a harsh environment. If you notice any signs of damage or the seal breaking, replace the terminal.
