Refrigerant: Pressure, Vacuum and Temperature Specifications
Temperature/Pressure Relationship
In a partially charged refrigerant container, refrigerant gas comes to the surface, which under particle formation becomes fluid. This occurs under
pressure and is known as gas pressure. Similar to R-12 refrigerant, the gas pressure of R-134a is temperature dependent.

WARNING!
Paint repairs on vehicles with A/C:
-

temperatures above 80 °C/176 °F.
-
Excessive heat will cause a pressure increase which could burst the system.
