Replacement Flame Arrestor Valve for Dual-Torch and Casting/Welding Systems

A must for all torch users! Should a flashback occur, flashback arrestors extinguish the flame, preventing fire from reaching the hydrogen generator. This replacement flashback arrestor is compatible with the L/80 Dual Torch and the L/160 Casting/Welding torch systems, and fits on the output line containing the hydrogen/oxygen fuel.
