What type of refrigerant is found inside the machine's gauges?

Explanation:
The gauges should be charged with the same refrigerant as the system. Using the same type inside the gauge set prevents cross-contamination of refrigerants and keeps readings accurate. Different refrigerants have different pressures and characteristics, so if the gauge interior contained a different refrigerant, it could mix with the system charge or skew pressure readings, making diagnostics unreliable. In practice, you want the gauge assembly to match what’s in the system to avoid any contamination and ensure measurements reflect the actual system conditions.
