It has been in use since the early 1990’s and now, in 2019, we are beginning to see it’s popularity wane with the rise of the new HFO refrigerant known as R-1234yf. R134a Pressure Gauge Chart. This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.

R134a Refrigerant. R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant. With the discovery of the damaging effect of CFCs and HCFCs refrigerants to the ozone layer, the HFC family of refrigerant has been widely used as their replacement. R-134a is the most common refrigerant found in automobiles today.
