In facilities handling multiple fluids, a visual management system is essential. Color-coding your K&G Machinery Camlock couplings prevents dangerous cross-contamination, reduces connection errors, and speeds up operator training. Industry conventions often include: Blue for Potable Water, Red for Fire Protection, Yellow for Hazardous Chemicals, Green for Oxygen/Compatible Gases, and White for Food/Pharma. K&G supports this in multiple ways: offering anodized aluminum couplings in standard colors, color-coded EPDM O-rings, and durable painted bands for stainless steel units. We recommend developing a site-specific color chart, labeling all storage areas and hoses, and training all personnel. A small investment in color-coding can prevent a major incident.
