Refrigerant R-421A is a non-ozone-depleting HFC blend engineered as a direct replacement for R-22 in existing systems. It delivers reliable performance while allowing a smooth transition away from ozone-depleting refrigerants.
One of the key advantages of R-421A is its broad lubricant compatibility. It can be used with mineral oil, alkylbenzene (AB), or polyolester (POE) oils, helping reduce retrofit complexity and minimizing system modifications.
When you purchase from CoolVora, you receive brand new, 100% virgin refrigerants that meet or exceed ARI-700 purity standards. Every cylinder is quality-tested to ensure dependable performance and system safety.
