Looking for the Pressure/Temperature chart for a 94 sport with front AC only. System is factory r-134a and my low side readings are lower than the standard chart pressures. I have the grey orifice and it had a grey one when I purchased the truck. I know some Explorers used a red orifice and I would like to confirm which one mine uses.

Thanks

I recently went through the AC system on my 94, and it had a brown orifice. Replaced with same. Also factory R-134a. These first gen Explorer AC systems are not the best. This is the fifth or sixth time it needed work.

As far as I know, it's all based on the ambient temperature.

93 (R12) to 94/95 (R134A) all show a red colored orifice tube.
