Which capillary tube can i use for an 404A freezer?

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.
