Magenta Gauge and Curve

R-134a US Overview Chart — Magenta Gauge and Curve

A silver dial sits above a magenta saturation curve, with two overview table blocks below the graph.

Use this chart to look up the saturation pressure of R-134a from a Fahrenheit temperature, then compare the equivalent Celsius reading on the same row. The 5°F spacing gives a broad overview rather than the finer steps of the detailed edition. This magenta gauge and curve version covers -40 to 180°F in 5°F steps.

The small curve shows the overall pressure-temperature trend; use the table below it to read the listed values for individual reference points. The 45 listed reference points use Fahrenheit, Celsius, psi gauge, bar gauge.
