Leak Sealers?

Waste of time? How does stuff like this not clog metering devices?

    I don't trust it Bob.

    These things have come and gone. I won't say that I have never seen them used effectively, but always for a short time until a replacement could be acquired. To the best of my knowledge, use of these leak stops will void any remaining manufacturer's warranty.

    Leak Sealers:

    My old High School Auto Shop teacher used to say, "You can't buy a mechanic in a can.".

    It's still true today. I haven't found one in 50 years.

    I would not use it.

    The product information states that the solution remains a liquid until it leaks from the system and, after reacting with the moisture in the air, creates a seal. From this, I can only assume that the humidity of the air surrounding the unit will have a direct effect on the performance of the product. In addition, if the solution crystalizes once it leaves the system, then it is only sealing the outside of the leak, no the entire leak. When we braze a fitting, we should be completely filling the fitting with filler material, not just the outside. Since high side pressures are, well, high, I am not certain that I would trust a "surface" repair.

    If the manufacturer of this product is reading this post, I would definitely welcome you to provide us with your take on the situation, as we all like to learn!

    Thanks and have a great summer!

    Confirmed what I already thought. Small leaks are a %^&* to find,and the easy way sometimes is enticing!

    leak freeze

    Went to a mini trade show last week and was given a sample of this product:


    On the box it says it doesn't use the moisture in the air to activate it. I have not tried it, and not sure I will, but one of our guys has a small leak in his car A/C that he hasn't been able to find. He may try this product.
