MaxWeld® Flash Back Arrestor, Oxygen, Torch Mount

316L Stainless Steel Filter (DF): The first line of defense, this filter traps dirt and dust particles before they can enter the internal mechanism, keeping your Flash Back Arrestor functioning flawlessly.

Non-Return Valve (NV): This valve ensures one-way gas flow, preventing dangerous backflow of gas into the torch or regulator.

Flame Arrestor (FA): In the unlikely event of a flashback, the flame arrestor acts as a final barrier, extinguishing the flame before it travels back into the hoses or tank.
