Firesafe Cannula Valve Oxygen Supply Tubing Connector (Male to Male)

COMPATIBILITY: This Firesafe Cannula Valve has a universal fitting at each end so it can easily be inserted between any two lengths of standard oxygen tubing, as well as oxygen cannulas with standard fittings like those sold on this site.

HOW IT WORKS: The Firesafe Cannula Valve is essentially a thermal fuse, comprising a spring loaded valve held open by a T-bar. The T-bar is situated downstream of the valve and supported by a fusible ledge of material. The Firesafe valve is actuated when the fuisble ledge softens as a result of heat from an approaching fire in the oxygen delivery tubing. Upon actuation the valve probe moves forward and an o-ring seals the valve, thereby isolating the oxygen supply from the fire.

USAGE: It is recommended that at least two Firesafe devices are fitted to each oxygen delivery circuit. The first, either a Firesafe Nozzle or Firesafe Cannula Valve depending on your oxygen setup, should be positioned close to the source of supply; and the second, a Firesafe Cannula Valve, should be positioned close to the patient. The Firesafe Cannula Valve provides no protection if a fire burns through the oxygen delivery tubing upstream of the device.

REPLACEMENT: The Firesafe Cannula Valve is maintenance free and has an intended life of 4 years. Dispose of any Firesafe Cannula Valve 4 years after the manufacturing date engraved on the device. Once actuated, the Firesafe Cannula Valve cannot be reset and must be discarded.
