No.
R22 gauges are designed for use with R22 refrigerant, and while they can technically be used to read the pressure of R416A, the accuracy may not be reliable. R416A has different pressure-temperature characteristics compared to R22, so using R22 gauges could lead to misinterpretation of the readings and potentially improper servicing. It's advisable to use gauges specifically designed for the refrigerant in use to ensure accurate measurements.

No, because R22 is a 'harmless' gas. Just observe the material safety data sheet (msds) and keep it on hand.

After 1992- r134A Before 1992- R22 but it need to be retrofitted for R134 if it hasn't been done already. It is ILLEGAL to use R22 in autos.

Mixing R22 refrigerant with R438A is not recommended. R438A is a replacement for R22, but it has a different composition and properties. Mixing refrigerants can lead to reduced efficiency, potential equipment damage, and difficulty in servicing the system. It's best to fully evacuate the system and charge it with the appropriate refrigerant.
The cost of 125 pounds of R22 refrigerant can vary depending on market prices and supplier rates. On average, you can expect to pay anywhere from $50 to $100 per pound for R22 refrigerant. Therefore, the total cost for 125 pounds of R22 could range from $6,250 to $12,500.
