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.
