R-421A Refrigerant is a high-performance HFC refrigerant blend designed as a replacement for R-22 in existing air conditioning and refrigeration systems after proper retrofit. It offers reliable cooling performance while eliminating ozone depletion potential (ODP), making it an excellent choice for extending the life of legacy R-22 equipment.
One of the key advantages of R-421A is that, in many retrofit applications, it can be used with the existing mineral oil or alkylbenzene lubricant, reducing the need for a complete oil change. Each factory-sealed cylinder contains 100% virgin R-421A refrigerant manufactured to meet AHRI Standard 700 purity specifications.
