Gray Dial Ribbon

R-134a Pressure Lookup Chart — Gray Dial Ribbon

A large silver dial overlaps an angled gray heading, with a white pressure lookup table beneath it.

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 dial ribbon version covers 0 to 200 psig in 5-psi steps.

The angled header separates the illustration from the banded table, so the data remains grouped in a rectangular reading area. The 41 listed reference points use psi gauge, Fahrenheit, Celsius.

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.
