25LB R449A (R-449A) Refrigerant Gas

R449A is a zeotropic HFO blend widely used in low- and medium-temperature commercial refrigeration. It is designed as a lower-GWP replacement for refrigerants such as R404A and R-507, and it is used in both retrofits and new refrigeration systems approved for R449A. Because of its broad acceptance across supermarket and commercial refrigeration applications, R449A remains a practical option for operators looking to maintain or transition compatible equipment with a lower-GWP refrigerant.
