Fluids / R-410A (saturated liquid)
Vapour pressure of R-410A (saturated liquid) vs temperature
R-410A saturated liquid from −40 to 60 °C — the high-pressure blend in most modern split systems and heat pumps, running roughly 60 % above R-134a pressures.
Vapour pressure in kPa, from -40 to 60 °C along the saturation curve. The chart and the table below are the same numbers; the table is the one you can copy.

Rows marked published land exactly on a source anchor and are the tabulated figure. The rest are this library’s interpolation between the two anchors either side — good enough to design with, and said out loud so you can decide that for yourself.
