Grayscale Phase Folio

R-134a Pressure Lookup Chart — Grayscale Phase Folio

A grayscale vessel and dark liquid layer accompany a white table panel with stacked gray edges.

This version starts with gauge pressure rather than temperature. Find a listed psig value, then read across for the matching R-134a saturation temperature in Fahrenheit and Celsius; the 5-psi spacing makes the pressure steps easy to follow. This grayscale phase folio version covers 0 to 200 psig in 5-psi steps.

The raised paper-style table panel separates the reference rows from the illustration and title above it. The 41 listed reference points use psi gauge, Fahrenheit, Celsius.

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.
