    Pipeline Flame Arresters

    Image of Product. Front orientation. Flame Arresters. Pipeline Flame Arresters.
    To prevent flashback in flammable gas pipelines, an internal flame-arresting element absorbs the heat from a fire to extinguish the flame. These valves are commonly used in pilot lines connected to waste gas burners.

    Arresters for Flammable Vapors

    Image of Product. Front orientation. Flame Arresters. Arresters for Flammable Vapors.
    Minimize fire hazard from flammable vapors. Mount an arrester to your vent pipe to stop flames from traveling back into your tank. If the ambient temperature reaches 165° F, the fusible links melt, and the cover closes to block flames from the arrester.
    Replacement Fusible Links—To reuse the arrester, replace the fusible links (sold separately).
