Autofrost is about 1/4th the cost of R-12.

High Performance
Autofrost will produce a 3 to 10 degree colder air temperature at the duct than R-12.

EPA Accepted
Autofrost X3 has been found acceptable by the EPA for automotive and fixed applications.

No Oil Change

All fittings and adapters contain "double ended" Schrader valves. (US) Federal Law requires use of unique threaded fittings for all alternative refrigerants. The unique threaded fitting must be attached with a permanent thread sealant (such as Loctite(TM)) or other means to prevent its removal. Extra R-12 service ports, not fitted with unique threads must also be rendered unusable.

Depressing the Schrader valve in the hose adapter, will in turn depress the valve core in the unique fitting, which will in turn depress the valve core in the original service port. Athough the original valve core in the A/C service port can be left installed, evacuation and charging with the alternative refrigerant will go faster if it is removed.

Unique fittings, can tappers and labels are available from ATC direct, call 800-622-5008.
