Which refrigerant is typically indicated by a colored cylinder?

The refrigerant R-12 is typically indicated by a colored cylinder, specifically identified by a traditional color coding system. R-12, also known as dichlorodifluoromethane, is usually stored in a light green cylinder. This color coding helps technicians and operators quickly identify the type of refrigerant they are working with, ensuring safe handling and appropriate use in various refrigeration applications.

In contrast, the other refrigerants listed each have their specific cylinder colors that differ from R-12. For instance, R-134a is commonly indicated by a light purple cylinder, while R-404A is designated with a gray cylinder. R-410A, which is used primarily in newer air conditioning systems, is typically found in a rose-colored cylinder. Understanding these color codes is essential for safe and efficient operation in the refrigeration industry.
