Blue Phase Ribbon

R-134a US Detailed Chart — Blue Phase Ribbon

A transparent vessel with blue liquid appears against a diagonal blue header, above the detailed Fahrenheit 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 blue phase ribbon version covers 0 to 120°F in 2°F steps.

The angled header separates the illustration from the banded table, so the data remains grouped in a rectangular reading area. 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.
