R-404A is compatible with certain oils, specifically polyolester (POE) and alkylbenzene oils, which are commonly used in refrigeration systems. It is essential to ensure that system components, such as seals and gaskets, are also compatible with R-404A to prevent leaks and maintain efficiency. Additionally, R-404A should not be mixed with other refrigerants, as this can lead to performance issues and potential damage to the system. Always consult manufacturer guidelines for specific compatibility information.
No.
No r404a is not compatible with r409a, r134a and 404a use the same lubricates and are compatible but r409a use a different lub making them incompatible
R-404A and R-134a are not compatible for use in the same system. R-404A is a blend of refrigerants, primarily used in low-temperature applications, while R-134a is a single-component refrigerant commonly used in medium-temperature applications. Mixing them can lead to reduced efficiency, system damage, and operational issues. Always consult manufacturer guidelines and refrigerant compatibility charts before making any changes to refrigerant types.
R-404A is not compatible with R-12 systems due to differences in chemical composition and operating pressures. While R-404A is a hydrofluorocarbon (HFC) refrigerant, R-12 is a chlorofluorocarbon (CFC), and their properties require distinct system components. Converting an R-12 system to use R-404A typically involves replacing the compressor, expansion valve, and other components to ensure proper functionality and efficiency. Always consult a qualified technician for refrigerant conversions.
For a 404A freezer, you typically want to use a capillary tube that is suitable for refrigerants with a similar pressure and temperature profile. Commonly, a capillary tube with a diameter of around 0.8 to 1.2 mm and a length that matches the system's requirements (usually between 2 to 4 meters) is used. Ensure the tube material is compatible with HFC refrigerants like R-404A to prevent leaks or failures. Always consult the manufacturer's specifications for precise requirements.
R-404A and R-22 are not directly compatible. R-404A is a blend of refrigerants that operates at different pressures and temperatures compared to R-22, which can lead to system inefficiencies and potential damage if mixed. If you're considering a refrigerant change, it's essential to consult with a professional to assess system compatibility and necessary modifications.

The boiling temperature of refrigerant R-404A at atmospheric pressure is approximately -46.5 degrees Celsius (-51.7 degrees Fahrenheit). However, this temperature can vary slightly depending on the specific pressure conditions in the system. R-404A is commonly used in refrigeration applications, particularly for low and medium-temperature systems.
No, you cannot directly substitute R-134a for R-404A, as they have different chemical properties, pressure levels, and applications. R-404A is a blend of refrigerants designed for low-temperature refrigeration, while R-134a is used primarily in medium-temperature applications, such as automotive air conditioning. Using R-134a in a system designed for R-404A may lead to inefficient cooling and potential system damage. Always consult manufacturer guidelines or a professional before making any substitutions.
Mixing 404A refrigerant with R12 is not recommended, as they are incompatible and can lead to system damage, decreased efficiency, and safety hazards. R12 is a CFC refrigerant, while 404A is a blend of HFCs that operates at different pressures and thermodynamic properties. Additionally, mixing refrigerants can complicate recovery and recycling processes, making it difficult to maintain compliance with environmental regulations. It's best to use the specified refrigerant for your system.
