    Have any of you used freon stop-leak ?

    And is so; what happened when you did?

    It sounds both too good to be true, and too scary to use. But a local supply house says they have been selling it for over a year and have had nothing but positive feedback from the customers.

    What have you experiences been in regard to using this type of product?

    My supply house says the same thing, but I dont believe it. I wouldnt put anything in a system that aint supposed to be there. I even hate dyes for leak detection.

    The only things that should be in a refrigerant circuit are refrigerant and oil. And with todays newer systems only refrigerant, no oil. JMH0
    To much work with too little time!!!!

    There was a thread concerning Super Seal leak sealer a couple of weeks ago:

    http://hvac-talk.com/vbb/showthread....ight=leak+seal

    I've had one experience related to the product. A restaurant that I serviced had a 5-ton Rheem evaporator with multiple pinhole leaks for which I quoted a replacement coil. The customer then called in another service company who used the sealer on it. The leaks indeed stopped, but a few months later (after he threw them out and called me back in ) I found the C163 filter-drier totally plugged.

    I had to recover the refrigerant to replace the drier, so I opted to use my old recovery unit and some old gauges so as not to goop up my good ones.

    I wouldn't use the stuff.

    My main concern is if it reacts with air/non-condensibles and your trying to stop a leak.....how do you remove all the air/non-condensibles in the system so it won't gum up.

    I tried it once and it didn't work....and it screwed up my gauges...The new place where I work we had one can left. When I went through all of my MSDS sheets I didn't have one for the leak seal.....it got tossed...even though it (the MSDS sheets) were easily found when I searched for a few other chemicals to update, I never planned on using it.

    I meant: opinions regarding Your use, not just what you project. <g>

    I feel the same way - how can some crap like this work?

    On the other hand - I said that for many years about things made of plastic and about epoxies. But I have since found that both are wonderful things. <g>

    The supply house (a major with maybe nationwide distribution) says they have been selling it for a long while and have had good reports back. So apparently there are at least Some success stories.

    I am just looking for empirical data from 'them what's doin' <g>

    BTW: I would conder a job where all the refrigerant leaks stopped, and the only followup required was a drier change-out, to be a complete success. <g>

    In looking around the web I found this:

    GM Bulletin No.: 03-01-38-001: March, 2003. “GM Service Operations DOES NOT endorse or approve the use of any aftermarket A/C system sealer, A/C stop-leak product or A/C seal conditioning product in any GM vehicle.

    It's sort of a website based on just the thread title. Even though this is in ref. to car cooling systems.

    What happened to your gauges ?

    What bad thing did the stop-leak do to them?

    The LP control takes care of the non-condensibles

    The suction pressure never runs below about 5 lb. - so there are no non-condensibles.

    Right after attaching to the system the needles stuck and wouldn't move. Maybe I did something wrong but I followed the direction including evacuating the lines before adding.

    I guess I never thought of the system not being completely empty. I will have to admit the one I added it to was an experiment because I also got high regards from the supply store. I see if it never went below 5 psi then the would be no way for non-condensibles to enter the system.

    What happens when you have to open the system up for something other then a leak? How about if no one has marked the system to have this inside . I hope it does not get used wide spread and only for something where there is no other pratical choice. I guess it is just one more thing to think about when your there for the first time after someone else

    Well the experiment in question in my case was for a system that we could not find a leak on and it would work fine once charged and then when next season came up it would be low again. You know thinking back on this system I don't really know what the heck it went through in it's past. Maybe someone can chime in on using it in a system that they knew most of the history on.
