Blue Machined Dial

R-134a US Detailed Chart — Blue Machined Dial

A silver pressure dial accompanies the pale-blue heading above a deep-blue, beveled Fahrenheit table frame.

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 blue machined dial version covers 0 to 120°F in 2°F steps.

The beveled border distinguishes the table from the heading, with alternating row shading helping you track a value across adjacent columns. The 61 listed reference points use Fahrenheit, Celsius, psi gauge, psi absolute.

Using this reference

The PDF preserves the one-page print layout. The matching Image is a full-resolution WebP rendering. These are finished reference sheets with fixed data and illustrations.

Gauge pressure uses a 101.325 kPa atmospheric reference. Saturation values describe the refrigerant relationship; equipment instructions determine operating and charging targets.
