    Problem with Nu-Calgon EasySeal

    I don’t use sealant very often. I would rather find the definitive leak and silver it closed. However, I have had two systems recently where I could not precisely locate the leak. So, I used sealant.

    The first time I used EasySeal 4050-08, I had no problem injecting it.

    The second time, I used sealant from a different supplier, and presumably it was from a different lot.

    I could not get the Direct Inject to release into the system.

    When I disconnected my hose from the Direct Inject tube, I lost the contents.

    So, I tried a second tube. I still couldn’t get the injector to work. I called the supply house, and they gave me a number for Nu-Calgon tech. support. The tech. support person suggested trying to let the sealant go back into my charging hose.

    So, I placed the middle of the hose below the level of the injector tube, and the liquid sealant flowed back into my hose. Fortunately, I had a ball valve on my hose. So, I closed the valve, and trapped the sealant in my hose. Then I removed the injector, purged air from the stub of the hose, injected the sealant and charged the system.

    Nu-Calgon was great about saying they would send some replacement products.

    Have you had any problems with bad check valves or short Schrader depressors in these injector tubes?

    I’ve had a couple that I had to slightly loosen the schrader depressor so it would make contact with the core

    I didn’t try that because I was worried about getting a shot of sealant in my face. The stuff burned on my fingers and in cuts. So, I definitely didn’t want it in my eyes.

    Easy Seal is worthless from my experience. Haven't seen it work even once among dozens of applications.

    I’ve had the opposite experience. But knowing where it might work is important. It will not seal a leaking mechanical connection. It Will seal a mid run coil leak

    Old thread I know but I just started searching to see what went wrong. I just tried it for the first time and had the same experience. I didn’t speak with tech support but I did end up doing the same thing you did. Let it fall back into charging hose and then injected it directly from the hose. It was very time consuming since I had never used it before and wasn’t sure exactly how it was supposed to work. I am going to take it back to the supply house and see what they say.

    Don't like it either,but we have had "some" success on systems where it looses let's say a lb over the winter. Don't matter if it's a 2 ton or a 5 ton system, it "may" work if the leak is very slight. A few years ago we tried it on systems where we found leaks in coils and the clients did not have the $$ to change it. "Let's try something" rather than gas and go, but we found it to become an unanswered prayer for the client.

    When this topic was discussed on another thread I was called a hack for admitting use of it. I only wish to inform those who seek information, real life experience.

    So the customer doesn't have the money to do necessary repairs but is willing to compromise his/her compressor. As a contractor that sounds like walking into a trap.
    Personally I'd continue with gas-n-go to buy more time till they could budget for the needed funds.
    I just don't understand why most guys using this stuff are claiming they can't find a leak. Especially in residential with two components and a continuous line set. It's not like refrigeration equipment that can become a meticulous hunt with what seems like endless possibilities.
    Even so I seem to always find the leak. How is that is just me that's that lucky ?

    What if the leak is deep inside the evap coil? You know it is leaking, just can't pinpoint where unless you rip it out and cut some fins.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    Then I would recommend replacing the coil and not jeopardise the entire system.
    Know if you could isolate just the evaporator and use sealer that would help but we know that's not gonna be the case.

    Somehow it seems you (and many others) feel that putting these products into the system is their death sentenance. Let me repeat, "I do not endorse, or no longer use these products." Today we tell the client that we have tried them and they're likely just throwing money away. However, as some have feared with this, let's call it snake oil. I have not witnessed a single compressor failure, but we are on the same page, better to have just the real stuff in there.
    Somehow I knew just sharing experience, Intended to deter techs from using the product, would earn me critic from my peers on this forum.
