    42 minutes of Ray wearing out the nitrogen regulator.

    I'll stick with my YJ and 20year old Robinair CRTools.

    Did you watch the whole thing LOL
    Looks like a job for valve core gripper man

    I have two older versions and two newer versions
    Have the same problem with the newer ones
    They said guys have dug out at the o-ring to loosen them up
    My new ones seem a little better after some use but they are tight and push open the valve like Eddie figured. If you pushed them on manually you almost needed pliers to get the core off the tool when they were new

    About 10 minutes was all I could stand.

    Your YJs are probably made by C&D Either way It's a win for C&D.

    CD core tools leak under vacuum , ok they do a great job of extracting cores. They leak.

    Show me.

    Pulled a 325 micron vacuum and it held for an hour.

    C&Ds are rated by the company down to 200 microns.

    Since I bought my C&Ds a month ago (with ball valve...not diaphragm packing gasket ..that type DOES leak) I have not exceeded the company design specs and all my vacuums have held.


    What are the specific conditions that you encountered a leaky C&D under?

    Appion is rated to 20 microns.

    I have a pile of CD and YJ crt's. I have a YJ vacuum tree that I only close for vacuum oil purposes because it leaks so bad.

    I didn't want those tools to not perform , but they did. Specifics ...if I have a system that is rising after pump down with " brand B " isolation valves and I change the valves to " Brand A " and achive an stable reading , then I have to assume that " brand B " let me down. If I go through this 5 times I then develope an opinion that " Brand A " is the only way to go.

    And do you need a 20 micron vacuum? Your vacuum might not have stabilized and you assumed it was a leak. If you reacted to it as a leak you would have used your pump again. y then the vacuum could have stabilized

    Exactly how long did you wait and how many microns did it rise before you switched CRTs?
    And you didn't specify if you had a ball valve or not.

    I have been having the same problem with my appion's. Tried to pull a core an had to go back to my yj. Hope this gets better over time. Where is Appion Chris in all this.
    You need to put the phone down and get back to work!

    Anybody want to trade their Appions for my C&Ds?
    I got two C&D that haven't got much use but they don't hold a core very tight anymore and are leaky. Other than that they're fine.
    I think they make rebuild kits for the C&D and I will take the ones that grip too tight off your hands.
    I think I could break them in under 42 min.

    LOL, you beat me to it.

    I have used YJ, C&D, and Appion. They all had trouble pulling the cores out, about half the time they won't grab them.

    The main difference is, Appions don't leak around the valve packing like the others did.

    What other kind of valve is there for crt? All I've seen so far have ball valves.
