Firesafe Nozzle Nipple Nut-and-Stem Adapter for Oxygen Tubing & Concentrators

DESCRIPTION

The Firesafe Nozzle is a thermal fuse designed to extinguish an oxygen delivery tube fire and stop the flow of oxygen if the tube is accidentally ignited. The Firesafe Nozzle is used in place of the Nipple Nut-and-Stem. Adapter found on most standard stationary oxygen concentrators, flowmeters, cylinders, and related products.

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.

HOW IT WORKS:
The Firesafe Nozzle 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 fusible 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.

COMPATIBILITY:
This Firesafe Nozzle adapter has a universal fitting compatible with a wide range of stationery and home concentrators including those from Respironics, Airsep, Invacare, Medline, Drive Healthcare, etc. It is not needed for most portable or travels oxygen concentrators.
