Sight glasses are not used on R-134a systems, because bubbles can be
present even when the system is fully charged. You HAVE to check with
gauges and you HAVE to correct for the evaporator temperature once you
read the gauge. There's no other way to properly service an R-134a
system. There's a pressure vs. temperature curve chart in the AC section
of every Factory Service Manual.
