Liquid = bubble (use for subcooling). Vapor = dew (use for superheat). Bold rows: 4 °C and 38 °C. Reference only: always verify with the manufacturer’s data and your gauges.

How to use

Choose Temperature or Pressure and type the number. The answer shows straight away.
Blends show two values: use vapor (dew) for superheat and liquid (bubble) for subcooling.
Tap °C · kPa for metric. Below 0 psig, pressure is in inches of mercury (inHg) vacuum.
Press Print pocket chart for a one-page chart (Letter or A4) for the van or the tool bag.

About this R-410A chart

This R-410A pressure temperature chart gives the saturation pressure for every degree, in psig with °F or kPa (gauge) with °C. As a blend, it has a liquid (bubble) and a vapor (dew) column.

Source: manufacturer and supplier charts (Chemours, Arkema, A-Gas). Reference only: always verify with the manufacturer’s data and your gauges.

FAQ

What is the R-410A pressure at 40 °F?

118.4 psig vapor (dew) and 118.8 psig liquid (bubble) at saturation, from the table above.

What is the R-410A pressure at 100 °F?

317.6 psig vapor (dew) and 318.5 psig liquid (bubble) at saturation.

Why does R-410A have two columns?

R-410A is a blend with very little glide (0.19 °F), so liquid (bubble) and vapor (dew) are almost the same. Use vapor for superheat and liquid for subcooling.
