Foam Sealing Plug - Small

SKU: #HMS1499

This golf ball shaped, water-activated polyurethane foam plug acts as a fast acting leak sealant for chemical containment.



Use these foam plugs as an economical, fast, leak sealing solution for sealing unpressurized pipes, storage containers, rail cars and even boat hulls. Kit includes golf ball 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 sealing plug may be applied below the water line.
