Flash Back Arrester Oxygen 3/8″
A safety device for oxygen lines with 3/8″ connections that prevents reverse gas flow and stops dangerous flashback flames from reaching the oxygen source. Features a non-return valve and a flame arrestor. May also include a thermal cut-off. Essential for safe oxy-fuel operations. Must be specifically designed for oxygen (right-hand threads)

Flashback Arrester Oxygen 3/8″
A flashback arrester for oxygen with 3/8″ connections is a crucial safety device designed to prevent the reverse flow of oxygen gas and, more importantly, to stop a flashback flame from traveling back up the hose and potentially reaching the oxygen cylinder or regulator. This helps to prevent dangerous explosions.
Key features typically include:
- Non-Return Valve: Prevents oxygen from flowing back towards the gas source.
Flame Arrestor: A porous metal component designed to quench a flashback flame by dissipating its heat. - Thermal Cut-off Valve (Optional): Some models may include a thermal-sensitive valve that shuts off the gas flow if excessive heat from a sustained flashback is detected.
- 3/8″ Connection: Indicates the thread size and type (usually BSP or NPT) of the inlet and outlet fittings, ensuring compatibility with standard 3/8″ oxygen hoses and equipment. These are typically right-hand (RH) threads.
- Durable Construction: Usually made of brass or another robust material suitable for oxygen service.
- Specific for Oxygen: Designed and marked for use with oxygen only, as fuel gas flashback arrestors have different internal components and left-hand threads.
- Mounting Location: Can be designed for mounting at the regulator end, the torch end, or sometimes inline.
Using a flashback arrester on your oxygen line is a vital safety precaution in oxy-fuel welding and cutting operations.
