In the HVAC industry, each refrigerant gas has a unique cylinder color code that helps technicians easily identify the type of gas they are using. Knowing the right color is important to avoid mixing gases, ensure safety, and maintain proper cooling performance.
Below is the complete HVAC Refrigerant Cylinder Color Chart for air conditioner and refrigeration technicians.
HVAC Refrigerant Pressure details
Note: HVAC refrigerant cylinder colors are usually standardized for quick identification, but in reality, some companies use different colors for branding or regional preferences.
For example, R32 cylinders are officially Sky Blue, but some brands like Daikin and Midea use Pink cylinders for the same gas.
Therefore, always check the label or gas type printed on the cylinder before refilling — color should be treated as a visual guide, not an absolute identifier.
Refrigerant Cylinder Colors
Identify the gas by its cylinder color.
| Refrigerant Type | Cylinder Color | Common Use / Application |
|---|---|---|
| R22 | Light Green | Used in older Split AC, Window AC, and refrigeration systems |
| R410A | Pink | Used in inverter & non-inverter Split and Central ACs |
| R134a | Light Blue | Common in refrigerators and car AC systems |
| R600a (Isobutane) | Light Brown / Beige | Used in domestic refrigerators (eco-friendly gas) |
| R32 | Sky Blue | Used in modern inverter AC units (energy efficient) |
| R290 (Propane) | Flame Red | Used in small refrigeration and eco-friendly AC units |
| R407C | Orange | Used in Split and Packaged ACs as R22 replacement |
| R404A | Orange-Red | Used in deep freezers and commercial refrigeration |
| R417A | Light Blue-Green | R22 retrofit gas for air conditioning systems |
⚠️ Safety Note
Always confirm the gas type before refilling or servicing any AC or refrigeration system. Mixing refrigerants can cause system damage, inefficient cooling, and safety hazards.
🧰 Technician Tip
Use proper manifold gauges and vacuum pumps compatible with the specific refrigerant. Each refrigerant works at a different pressure range, so correct tools ensure accurate performance.
🏁 Conclusion
Knowing the refrigerant cylinder color codes helps HVAC technicians work faster and more safely. Whether it’s R22, R410A, or eco-friendly gases like R600a and R32, always identify the right color before use.
