Violet Gauge and Curve

R-134a US Detailed Chart — Violet Gauge and Curve

A silver dial tops a violet heading, with a Fahrenheit-based curve separating it from the detailed reference table.

This chart gives a closer-spaced view of the R-134a pressure-temperature relationship, using 2°F increments. Follow a Fahrenheit row across to compare its Celsius equivalent with both gauge pressure and absolute pressure in psi. This violet gauge and curve version covers 0 to 120°F in 2°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 61 listed reference points use Fahrenheit, Celsius, psi gauge, psi absolute.
