The Rupture Seal can address holes as small as 4mm (5/32in), as large as 64mm (2.5in) in diameter, and gashes up to 100mm (4in) in length. However, we are always improving our capabilities and further sizes are under consideration. If you have a requirement, let us know! The Rupture Seal deploys in seconds, even faster with training and experience. They are temporary measures intended to last upwards of 10 hours in the rupture.
