FOUR Connect 4-690382 STAGE3 OFC M8 Ring Terminal 20mm2, 2x Blue + 2x Black

Four Connect cable lugs set a unique standard among auto hifi installation material. They have quality heat shrink tubing as an insulator instead of the usual rubber or plastic sleeves. Shrink tubing protects the connection from oxidation much better than loose plastic or rubber sleeves. 90% of manufacturers make their eyes or forks from brass, which has more resistance than copper. The reason is simple, brass is much cheaper. For heavy current connections, it would be wise to use real copper to ensure the best connection and conductivity. All Four Connect Stage3 lugs are made from 100% OFC copper and are the highest quality lugs on the market!
