Liquid = bubble (use for subcooling). Vapor = dew (use for superheat). Negative kPa = vacuum. 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-417A chart

This R-417A 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. Below 0 psig the °F table shows inches of mercury (inHg) vacuum.

Source: manufacturer and supplier charts (Chemours, National Refrigerants). Reference only: always verify with the manufacturer’s data and your gauges.

FAQ

What is the R-417A pressure at 40 °F?

54.0 psig vapor (dew) and 63.4 psig liquid (bubble) at saturation, from the table above.

What is the R-417A pressure at 100 °F?

170.1 psig vapor (dew) and 184.6 psig liquid (bubble) at saturation.

Which column do I use for superheat and subcooling?

Use vapor (dew) for superheat and liquid (bubble) for subcooling. R-417A has 7.14 °F of glide at a 40 °F evaporator, so the two columns differ.
