R-421A Refrigerant 25 lb.

R-421A is a non-ozone-depleting refrigerant blend developed as an alternative to R-22. It can be used with several commonly encountered refrigeration oils, including mineral oil, alkylbenzene (AB), and POE oils, making it suitable for a range of applications.

R-421A can be used in certain air-conditioning, medium-temperature and high-temperature refrigeration systems across residential, commercial and industrial environments. Always verify system compatibility and follow the equipment manufacturer's specifications before installation or retrofit.
