OxySafe2 Firesafe Valve – Bidirectional Thermal Fuse for Oxygen Safety
Protect what matters most with the OxySafe2 Firesafe Valve. This advanced inline safety device is a thermal fuse designed to automatically stop the flow of oxygen and extinguish fires in oxygen delivery tubing before they can reach the patient or oxygen source.

- Recommended dual installation: Place one near the patient and one near the oxygen source for maximum protection.
