Technician A says R-134a and R-12 refrigerant gauge manifolds can be interchanged. Technician B says because of differences between R-134a and R-12 gauge manifold calibrations, they cannot be interchanged. Who is right?
A. A only.
B. B only.
C. Both A and B.
D. Neither A nor B.

Answer (1)

Technician B is correct; R-134a and R-12 refrigerant gauge manifolds cannot be interchanged due to differences in calibrations and pressure readings for each refrigerant. Using the incorrect gauge can lead to inaccurate results and possible damage to refrigerant systems. Therefore, it's essential to use the specific gauge manifold designed for the refrigerant being serviced. ;
