The R-134a and R-1234yf pressure charts are for guidance when using A/C Pro ® recharge kits, refills, and gauges. The charts are intended to help provide an understanding of a vehicle’s air conditioning system pressure, which can be helpful during the diagnostic and recharge processes.

Basically, this 134A PT chart tells you what is the pressure of R134A refrigerant at certain temperatures. The charts start at the low end (-49°F) and tell you the pressures all the way to the high end (150°F). Example: What is the pressure of 134A freon at 85°F?

Note: Underline figures are in. mercury vacuum.

These psig readings for R-134A are what you'd expect the pressure of the gas to be in an enclosed container at the temperature given and at steady state. R-134A Refrigerant Pressure / Temperature Chart & Table Downloads

This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.
