Which color code is associated with R-502?

Explanation:
Color coding on refrigerant cylinders helps technicians quickly identify which refrigerant is inside so they don’t mix types and contaminate systems. In this standard labeling system, R-502 is associated with purple. This association aids safe handling, charging, and service, since different refrigerants require different oil types, pressures, and compatibility. The other colors are used for different refrigerants in the same coding scheme, so they don’t indicate R-502.
