    • Options offering no risk of metal contamination
    • High flow valve design in a compact package
    • Disconnects under pressure to speed servicing and reduce risk of injury
    • Made of polypropylene and PVDF for broad chemical compatibility

    The CQG Series feature our patented pressure-balanced, non-spill design. Molded virgin polypropylene and a 100% metal-free flow path provide extensive chemical resistance and exceptionally high flow capacity, allowing instant disconnects (and reconnects), even under pressure.


    With a metal-free flow path, Viton® seals and other high purity features, we make your chemical handling cleaner, faster, safer and smarter.

    Dual Containment Flare Nuts

    The ChemQuik Dual Containment System easily “double contains” critical chemical lines, protecting plant and personnel in case a primary process line ruptures or sweats. The system provides a protective secondary line to catch any fluid and routes it to a safe location. The ChemQuik system is compatible with any CQ Series with fine thread flare terminations or a common flare style fitting. For more information on the ChemQuik Dual Containment Flare Nuts, see pg. 141 on the CPC catalog.
