static pressure equalization time frame.

What is the typical time for pressure to equalize after shutting down ac system. I am seeing 4-6 hours before they do which I think is to long, any idea what could be the cause. Thanks 2007 VW Sanden compressor.

Re: Valve cores

Thanks for the responses. So as I am understanding the posts made here the cap it to protect the valve core and prevent small leaks that might get passed the valve core but will not hold back the pressure of a complete valve core failure.

Valve cores

Thought I ask this question here because you people have have always been helpful and know you stuff. What is the primary sealing device for the service ports? I believe that it would be the valve core and it seals and that the service port cap is to protect the core valve from any damage & dirt...

Stupid question on leak detection

Is it legal to add a few oz of R134a to an empty system to try to locate the leak/s with a sniffer.
