    Leak Lock Bandit Strikes Again

    So the high side Schrader leaks. I was able to immediately identify it as the cause of the leak because the service valve cap was put on with leak lock and covered with oil. Plus it leaks so bad, that once the compressor and fan shut off, you can hear it hissing.

    So I go to change it, but unfortunately there is so much leak lock in there, I can't even get my core tool on it. Plus that stuff is dried rock hard. Finally after about 10 minutes of picking out rock hard leak lock with a screwdriver, I was able to get my core remover on there and change it.

    The blue goo has it's place, but not someplace like that where it would have been easily repairable.

    I also found a unit with leak lock smeared all over the schrader fitting, kind of like that one. The difference was that it was one of those big oversized fittings that carrier uses on some of their rooftop units. It still leaked, but at least I could understand it in that situation.

    If more government is the answer, then it's a really stupid question.

    I bet a tube lasts me 1 year+. There is a time and place for it and used improperly, it is a freaking pain! I had an idiot tech PAINT this on most of the service valves in a parallel rack, not in the threads of caps, just painted the outside! Imagine my excitement walking into this.

    I like a little in the threads of of new brass service ports, not only to seal, it acts like a thread locker. Mind you, I use very little.

    Well now I ruined it for everyone, my boss found out about this, and now we aren't allowed to use leak lock anymore.

    Oil plugs and pipe thread fittings for pressure controls on semi-hermetic compressors. Nylog on the rest.

    Why would I try to get them out ? They are a pipe thread to SAE fitting. Never had to remove one accept to reuse it on a compressor change out. At that point there is nothing to leak out

    That's why I love my tubing pinch tool. Can replace those stub access fittings without pulling all the gas out.
    I do three kinds of work.
    1 - Good - 2 - Fast - 3 - Cheap
    Pick two

    I thought I worked with the only guy that did leak lock art. It won't hold up on r22 for some reason. Nylon won't hold up when it gets too cold. Loctite 554 is the only thing I have found to hold up in extreme temps.
