What is the appropriate color code for R-12 refrigerant?

The appropriate color code for R-12 refrigerant is indeed white. This color coding system is established to provide a quick and easy way for technicians to identify different types of refrigerants in HVAC systems.

R-12, which is a chlorofluorocarbon (CFC) refrigerant that has been widely used in refrigeration and air conditioning systems, has been identified specifically with the color white. This helps prevent any confusion during service and maintenance work, ensuring that HVAC professionals can quickly recognize the type of refrigerant they are dealing with and avoid any mishandling.

The color codes for refrigerants are essential for safety and efficiency in handling, as different refrigerants have different properties and regulations regarding their use and disposal. In contrast, other refrigerants correspond to different colors in this coding system. Familiarity with these codes is a crucial aspect of HVAC training and practice, aiding in proper service techniques and compliance with environmental protection guidelines.
