North American Rescue HyFin® Chest Seal (Individual / Occlusive)

When air gets into the chest, you need to stop it—fast.

The HyFin® Chest Seal (Individual) is a non-vented, occlusive dressing designed to treat open chest wounds by sealing the injury and preventing outside air from entering the chest cavity.

This version creates a complete seal, making it ideal for immediately covering penetrating injuries and stabilizing the casualty. Built with an aggressive, medical-grade adhesive, it sticks in real-world conditions—blood, sweat, hair—it holds when it matters.

Application is simple: wipe the area, peel the liner, place over the wound, and press firmly to seal.

Compact, reliable, and field-proven, this is a must-have for any serious trauma kit.
