When I fill it with nitrogen after i vacuum the system down what pressure should i go to for the nitrogen on a r12 system??

I pulled my condenser today it was dirty in there but not bad. now the fins on the condenser at the bottom are fairly bent I dont know if I can straighten them. If I cant should I go back with a 91 condenser or is there a year model that has a better one?

I think you can use a radiator comb to fix those fins.

Hey guys i need a part number For the Square cross-section O-rings (The black one ) that goes between The compressor and the AC hose flange. All I can find are round ones The factory ring is 0.120" thick The aftermarket round cross section one is 0.140" thick. Any advice on what I should use. if I cant find it should the round ones be adequate?

Excellent question

Where do you find the green O rings?
I had the green O-rings on the evaporator connections but maybe the .120" thickness.



I dunno if this helps but there are a lot of AC O-ring kits on Ebay under the name Santech Industries.

I got the green ones at a local A/C parts supplier. I also Bought that kit from orilliys and none of those work on the compressor to hose flange union point.

I could not figure where my leaks where so am sitting here with the professionals
They installed new green o rings on evaporator and on my new drier.
They then pulled 30 inches vacuum and all is perfect.
Except they ran out of R12 here in CA.
So i will add that myself as AC is holding vacuum perfectly.

I had a very peculiar AC leak on the line that goes from compressor to the drier (drier end). That large female threaded nut gauled inside with aluminum and we thought it was tight when in fact it was gauled and would not tighten the O ring on that end. The nut was tight but the AC hose/O ring you could still wiggle and turn. After figuring that out, things went smoothly and we got and held perfect vacuum.

Well I found a great oring for the compressor it fits and compresses beautifully. Its made of BUNA-N rubber and is impervious from all oils and fuels. Also dose the a/c system have 8ozs of of oil in it?

This is the oring
