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-600a chart

This R-600a pressure temperature chart gives the saturation pressure for every degree, in psig with °F or kPa (gauge) with °C. Below 0 psig the °F table shows inches of mercury (inHg) vacuum.

Source: supplier chart (A-Gas), checked against NIST. Reference only: always verify with the manufacturer’s data and your gauges.

FAQ

What is the R-600a pressure at 40 °F?

11.9 psig at saturation, from the table above.

What is the R-600a pressure at 100 °F?

57.9 psig at saturation.

Does R-600a have glide?

No. R-600a is a single-component refrigerant, so one saturation pressure works for both superheat and subcooling.
