R-438A (MO99) 25 lb Refrigerant Cylinder is an HFC blended refrigerant designed primarily as a retrofit replacement for R-22 in residential, commercial air conditioning, chillers, and medium/low-temperature refrigeration applications. It is commonly marketed as Freon™ MO99 / ISCEON® MO99 and is intended to provide an easier transition from R-22 systems while maintaining compatibility with many existing lubricants.
