Not enough information available on Freezone, ES12R, OZ-12 or ADAK-12
to compute temperature/pressure relationships.

Note: As of October, 16 1996, some refrigerants listed were not legal
for automotive use. Always check legality of a certain refrigerant before its use.
This can be done by calling the

EPA OZONE PROTECTION HOTLINE
(800) 296-1996
