Rupture Seal products are available in 4 sizes and compatible with over 40,000+ substances - more than any other product on the market. In just seconds Rupture Seal creates a safe mechanical seal to plug even rough, unclean or splintered surfaces, making it the best all-in-one solution for the control of fuel and chemical spills, for hazmat and first responders, transport container and saddle tank ruptures, forklift punctures, pipe leaks, breaches and more. Faster to deploy than putty compounds, urethane foam or wooden/screw plugs - and easier to remove after the fact. And unlike sealing tape, Rupture Seal is compatible for fuel leaks.
