The Hercules Shutout, MPN 25420, is designed to seal and lubricate manhole covers to minimize inflow. This product is suitable for use with most manhole installations and enhances existing seals by filling gaps and defects within the manhole cover and seat. It forms a water-resistant barrier, which reduces corrosion and ensures easier and safer removal of the manhole cover.
This sealant is ideal for professionals looking to maintain manhole integrity and safety.
