ive crossed used 404 in a 134a motor and vice versa. 134a in 404 and r410 motors the big deal is to use ester oil which mixes with all 3 oils. miscible.

404 delivers a higher head pressure. so 404 in 134a motors are not real prepared for start-up. (warning).

What else can I help you with?

Is r-404a compatible with 134a?

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.

Can you substitute 134a for 404a?

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.

Could you mix 404a refrigerant with R12?

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.


Mixing freon 22 with 404A would it work?

No, mixing refrigerants like Freon 22 (R-22) and 404A is not recommended as it can create issues with system performance, efficiency, and potentially damage the equipment. It is important to use the correct refrigerant specified by the equipment manufacturer to ensure proper operation and avoid any safety concerns.
