Unacceptable Substitutes (2)
Name (1) Date Manufacturer Reason
OZ-12® 3/18/94 OZ Technology Flammable blend of hydrocarbons; insufficient data to demonstrate safety
R-176 3/18/94 Arctic Chill Contains CFC-12, which is inappropriate in a CFC-12 substitute
HC-12a® 6/13/95 OZ Technology Flammable blend of hydrocarbons; insufficient data to demonstrate safety
Duracool 12a 6/13/95 Duracool Limited This blend is identical to HC-12a® in composition but is manufactured by a different company
R-405A 6/13/95 Greencool Contains a perfluorocarbon, which has extremely high global warming potential and lifetime
  1. Many refrigerants, including R-401A (made by DuPont), R-401B (DuPont), R-409A (Elf Atochem), Care 30 (Calor Gas), Adak-29/Adak-12 (TACIP Int'l), MT-31 (Millenia Tech), and ES-12R (Intervest), have not been submitted for review in motor vehicle air conditioning, and it is therefore illegal to use these refrigerants in such systems as an alternative to CFC-12.
  2. See text for details on legality of use according to status
  3. Although some blends contain flammable components, all blends that are Acceptable Subject to Use Conditions are nonflammable as blended.
  4. Freezone contains 2% of a lubricant
  5. HCFC-22 content results in an additional use condition: must be used with barrier hoses
