22-A Substitutes Refrigerant - Second generation replacement for R407c, R404a and MO99

22-A Substitutes Refrigerant - Second generation replacement for R407c, R404a and MO99

Product Review (submitted on July 15, 2013):

The system had a large leak causing all of the R22 to be lost. I repaired the leak, vacuumed the system and filled it with 22a using the same pressures as R22 - system works great!
