Monochrome Dial Header

R-134a Pressure Lookup Chart — Monochrome Dial Header

A large silver pressure dial sits beside the dark heading, with two pressure-led table blocks below.

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

The rounded heading leaves the reference table in its own white panel, separate from the equipment illustration. 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.
