3M™ Scotchlok™ Ring Tongue Terminal ensures an ideal fit and offers reliable performance. The brazed-seam barrel is covered by an adhesive-lined polyolefin tubing to offer moisture-seal protection. It withstands temperatures of 221 degrees Fahrenheit (105 degrees Celsius). Its electrolytic copper construction offers good conductivity and a tin-plated finish resists corrosion. Its ring shape is the safest and most reliable, because it cannot be removed unless mounting screw is removed. 3M™ Scotchlok™ Ring Tongue Terminals are colour-coded for quick and easy identification of the wire size required.
