Re: Leaking sight Glass!?!!
Hi The MG Pony,
I once had leakage form a sight glass on a receiver. This sight glass was flare type (the glass part).
Otherwise not seen leakage from them.
Cheers
Re: Leaking sight Glass!?!!
Ya thats where it was leaking from! Around the glass:eek: It was a R-134a system so pressur wasn't even that high! Orrigionaly R-12 but the tech who last worked on it replaced the sight glass comp, and F/D.

Sight glass do leaks due to gaskets, you have already replaced with a new one, Why not open old one and check it,

Re: Leaking sight Glass!?!!
When you say it held a vac, was this on a proper torr or milli bar gauge, and for how long?
Re: Leaking sight Glass!?!!
It could hold a vacuum as the seal can get pulled into/onto the mating surfaces/threads.
Re: Leaking sight Glass!?!!
800 mTorr for a fiew minutes (Ya My pump is gimped I think)
Re: Leaking sight Glass!?!!
Brian is right ,have seen this many times on package chillers.

I swapped out with a new sight glass and F/D and it's purring away, but was rather curious that a sight glass was leaking!
Quite a common fault.
It did not show on the vac as others stated because it pulled itself in and sealed.
Now you've found it once you will Know to look for it again:)
Cheers taz.

Ya, first time for me too never would have sustected a sight glass, a drip fell on it as I moved the brush to the other flare and noticed slight bubles so put a full drop on and well!
