    Welding Gas Flashback Arresters for Regulators

    Attach these arresters to the outlet connection of a regulator on a torch that cuts steel up to 11" thick. Arresters extinguish flames and have a check valve to stop reverse gas flow. They are reusable; resetting is not required after flashback.

    Flashback Arresters

    Arresters with right-hand threads are for use with oxygen.
    High Flow Flashback Arresters—High-flow arresters give you twice the airflow rate compared to standard flashback arresters when they’re used at the same inlet pressure. They are often used with larger torch tips.
    Quick Disconnect Flashback Arresters—Quick-disconnect arresters have a fitting that connects and disconnects them from your torch, so you don't have to thread these arresters on and off with a wrench.
