How many inches down the side are recovery cylinders marked?

Recovery cylinders are marked with color-coded sections to indicate their contents, specifically the various refrigerant categories they can safely hold. The marking is typically located 12 inches down from the top of the cylinder. This specification is important for technicians to easily identify the type of refrigerant contained, promoting safe handling and preventing contamination. Additionally, the 12-inch mark aligns with industry standards to ensure that those working with recovery cylinders can quickly ensure compliance with regulations and best practices for refrigerant recovery and recycling. Having this clear demarcation helps to maintain safety in HVAC practices by minimizing the risk of mixing incompatible refrigerants.
