Saturation Pressure-Temperature Data for R134A (psig)*. Temp (°F)
Printable PDF. Temperature (°F): Temperature (°C): R134A Pressure (psig): -49°F. -45.0°C.
For on-site use, we include a printable R134A PT chart in PDF form at the end of the article. To help everybody out, we have explained some examples about what is the 134A pressure on 75°F, 80°F, 90°F, and 100°F days below the PT chart for R134A.
