In short, die cut means precise. Each gasket is cut to form a perfect, airtight seal when the lid is locked. Fires can be unpredictable so we've installed them in three different places for you.

We've added a bead of special silicone around the inside of our waterproofing system to ensure not one drop of water sneaks inside, even in the worst case scenario.

Expands 7 times its own size to keep heat and water out. Once expanded the seal acts as a glue to hold the lid closed until the heat subsides.
