Ambient R12 Chart
I need an ambient temp chart for charging R12 ac system. Needs to have factory specs for high/low pressures on a system for a 71. I know 134 charts are on net but is R12 the same readings? A pic or linc will do. Thanks.

Temperature/pressure charts are online for all refrigerants. The high and low specs will depend upon the temperature and humidity (as well as air flow through the condenser). This is where the gauge set comes in. Though you could just evacuate the system and charge it by refrigerant weight, which would be ideal.
