R-134a Pressure Lookup Chart — Gray Molecular Medallion

A grayscale molecular model sits inside a dark circular medallion above the multi-unit pressure lookup table.

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 gray molecular medallion version covers 0 to 200 psig in 5-psi steps.

This multi-unit version includes additional pressure columns, allowing the same saturation row to be compared across more unit systems. The 41 listed reference points use psi gauge, Fahrenheit, Celsius, bar gauge, kPa absolute.

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.
