Title: R12 leak seal - still available?
Post by: SuperSix on August 24 2011, 10:12:01 PM: There's a very slow leak in the 87T's A/C. I haven't converted to 134 yet, and just out 4 cans of R12 in it. (Yes, I know, stupid to put it in a system I know has a leak, albeit a very slow one - I was bored)

Are there any R12 leak sealers that work and won't damage the system?

Tried it once and never will again. Stuff sucks to say the least and I had to replace my compressor because of that shit.

Yep - that's what I was worried about. Once it stops cooling I will convert it over to R134.

I guess they didn't do their homework on the leak stop. Are you positive your compressor wasn't on its way out anyway Charlie?

No, no idea.. The compressor > accumulator lines are relatively now, and I replaced all of the orings when I redid the AC. Must have been 6 years ago or so.

It may have been but Freeze12 is not a standard substitute. It's a blend and doesn't distribute the oil right throughout the system. AC was working fine before I added it and a week afterwards the compressor was trash. Found out about the stuff after I'd used it from another tech.

When the R-12 is drained out can it be emptied into any empty tank even if it had 134 in it at one time? I dont know where to find clean tank for a decent price except an empty BBQ tank?
