Cable pulling lubricant is a specialty product designed to significantly reduce friction between the cable and the inside of a conduit. Using a lubricant is highly recommended for longer pulls, installations with multiple bends, or when working with heavy cables. The reduced friction lowers the pulling force required, which protects the cable jacket from physical damage and minimizes the risk of a failed pull. We recommend using a water-based gel lubricant, as it provides an excellent low-friction coefficient and is compatible with a wide variety of cable jackets. The best lubricant is one that is slow-drying and leaves a thin, slippery film that retains its lubricity throughout the entire pull.
