Chest seals are critical for treating penetrating chest injuries in the field. At Off Grid Warehouse, we offer compact, high-performance options like Hyfin® and Foxseal®, rusted by military and tactical medics worldwide. These seals are vented or non-vented, sterile, and feature strong adhesive that works even in tough conditions. Designed for rapid deployment, they prevent air from entering the chest cavity while allowing air and fluid to escape, helping prevent tension pneumothorax. Whether you're building an IFAK or outfitting a trauma team, our chest seals deliver reliability when it matters most.
