Use these large foam plugs as an economical, fast, leak sealing solution for sealing unpressurized pipes, storage containers, rail cars and even boat hulls. Kit includes football shaped plug infused with water-activated polyurethane foam, along with nitrile gloves and instructions for use. Foam plugs are initially pliable so they can be inserted into a damaged surface but quickly expand and harden to seal the leak. Multiple plugs may be used for larger holes and the foam plug may be applied below the water line.
