Re: pressures won’t equalize to saturated pressures with system off

That’s the thing, I forgot to mention that it’s not blowing cold and the compressor isn’t engaging. Why would the pressures not be equal? Retard is on the opposite side of the gauge than where inHG is for pulling vaccum. Gauge only reads to 130psi and then goes into retard~350psi. The system is off ...

pressures won’t equalize to saturated pressures with system off

2011 Audi A3 and in 104°f temps with vehicle off the low side won’t equalize with the high side. Low side show 105psi and high side 145. Shouldn’t my blue gauge be reading in the “retard” area?

Re: R134a mixed with pag and poe

So when I was recovering the refrigerant I had both the low and high side open on my manifolds but I was throttling the flow at my recovery unit. In hindsight I probably should have had the high side closed until the pressures dropped to avoid sucking in liquid but there was probably about 3 seconds...

Re: R134a mixed with pag and poe

I did not use an automotive machine. I did use a manifold gauges with a sight glass and there was a little bit of neon yellow/green refrigerant which would be oil and not leak dye, right? In the tank, if there is any oil would it be sitting on top of the refrigerant?

R134a mixed with pag and poe

Hi all, new to this forum. Just have a quick question. I had R134a stored in my recovery tank that’s previously been in systems using pag46 oils. I was recovering ac out of my 2014 Honda Accord Hybrid which uses nd-11 Poe oil, which I realized after recovering all the refrigerant into my tank contai...
