AC Fittings seal? on York '87 4kq compressor

[Ben Swann]

Ti,

I found the fittings do take O-rings, so my question is answered.

I have done a few R134a conversions so far with these - works OK, tho not
great.  I can always do R-12, but hate to rick wasting my R-12 on a system
that may not be sealed perfectly.  I would not have touched this for an
engine swap, but P.O. in a hurry to yank the engine, disconnected the system
and now I'm trying to put it all back again.

I didn't want to go charging with R-12 only to find I might have a leak, but
the compressor should be good, and the condensor is brand new.

No way in H*** am I shelling out for a new compressor.  I have enough laying
around here that I should be able to get one of them working with R134a.
I've done a couple and if the compressor was good, then the system worked
OK.

Are there any particular compressors from the older cars that would work any
better, or is it just a general thing that the older compressors don't work
well with R-134?  How much are the new compressors, if I may ask?

I'd like to save what little Freon I have left for known working systems
that just need a charge every couple of years, if that.  This project has
consumed far more of my resources than I ever intended and I am just trying
to get it completed finally so I can move on.

Ben
