Can you use the same gauges for different refrigerant?

No, you cannot use the same gauges for different refrigerants without considering compatibility. Different refrigerants have varying pressure-temperature relationships and chemical properties, which can lead to inaccurate readings or potential damage to the gauges. It's important to use gauges specifically designed for the type of refrigerant being serviced to ensure safety and accuracy. Always check the manufacturer's specifications and use the appropriate equipment for the refrigerant in question.
