Such a thing as "safe" stop leak?

Not that Im ready to use it- just wondering, as EZ chill claims on their label "system safe". Softens o rings. Do all companioes selling this use the same type stop leak? Oxygen sensitive such as whrn one opens up a system for repair, the oxygen cruds up the whole inside of system?

Thanks.

I think the problem with these so called "o-ring conditioners" is that they don't know when to stop. They will eventually turn every seal in the system to a soft goo. They are actually nothing more than a rubber solvent. In the long run, it will cause the repair to be a lot more expensive. You will have to change all the seals, including the ones inside the compressor. Run away from that stuff.

The 'seal expanders' may not present a serious problem to the system, but that being said....if the system has a leak....repair the leak...this is the best method. Stay away from all these 'magic in a can' repairs. Just repair the darn thing.

Right, ice, and fixit, I agree to stay away- just wanted the opinions here. But isnt the real risk of stop leak the gunk it forms inside the system and not so much the softer seals? Gunk all over- saw pictures of this somewhere.........(dont wory, Imnot gonna use the stuff)

Kind of dumb to use an O'ring in an AC system in the first place, in particular on that very hot high side. All you will find is dust, rest of it is baked on as hard as a rock. Adding additional oil to a system is never a good idea. Already been proven a thousand times that oil does not cool.
