About Refrigerant PT Chart

Refrigerant PT Chart is built by a working refrigeration and HVAC technician who got tired of hunting for a clear PT chart on a phone, and of supply houses no longer handing out fold-out PT cards.

The site does three things: a quick PT lookup for 19 common refrigerants, a superheat and subcooling calculator, and printable pocket charts. Blends show liquid (bubble) and vapor (dew) values, and every page works in °F/psig or °C/kPa.

The tables are checked against current manufacturer and supplier charts (Chemours, Honeywell, Arkema, A-Gas) and the NIST reference data. They are a reference only: always verify with the manufacturer’s data and your gauges.

No sign-up, no tracking, free to use. Found a mistake or want another refrigerant added? Email hello@refrigerantptchart.com.
