Great question! I'll go one further- does anybody have a link to something that shows the whole ac system in an exploded view, or something similar?

AC o-ring kits have a bunch of any size you should need for about $15 dollars. Locations? Cant say, but anywhere two lines or parts meet. Pretty easy to tell. I have replaced AC o-rings on entire systems many times.

Get a free subscription to the Mercedes-Benz EPC (Electronic Parts Catalog). It will show what you need, though it is still not always 100% clear what seals go where. Sizes of o-rings (seals) depends on model and even VIN within that model.

a/c system is pretty straightforward.
compressor has two o-rings on the manifold. unless your compressor has been changed... then it could have spacers/manifold/god knows what else... the big lines go to a fitting on the condenser that has an o-ring, out of the condenser there is a fitting with an o-ring, from there it goes to the dryer with an o-ring and three small o-rings for the sensors and the line out, from there it goes to the expansion valve with an o-ring, then out of the evaporator back into the expansion valve with an o-ring, then the large line has a connection in the firewall with an o-ring, and if you have a 123, another line with another o-ring, if not, then the line goes right to the compressor on a 126. other systems will be similar. also the R4 compressor has a valve on the back of it, with a snap ring, that could leak also, with an o-ring under it... if it's not leaking don't muck with it...

Will O rings from 134a work for 12?

Why has no one mentioned Nylog ?
I think the color does matter on that....

You want green o-rings. If you disconnect anything, you put new ones in! I was told to use a VERY small amount of silicone grease to prevent binding when coupling the two parts. Not sure if that is standard practice, but I had no issues.

the O-rings on the compressor are a no brainer, I just don't want to have to go back through the whole system to replace them all.
