    What I've found is even if the core doesn't come out you can still tell if you got it unscrewed, you can then usually valve it off take out the plunger, pop the valve open real fast and it will shoot the core out.
    I got tired of fooling with it and just use my YJ plunger, it works everytime. Well, except for those weird valve cores on goodman packs I just pull a vac the old fashioned way on those. Why does goodman use that type of valve core?

    I had that problem last year. Appion sent me new plungers. All is good now.

    We have a range of valve cores that EVERY tip is tested on, and the tip has to grab the core on the first try to pass the test. Either you have a "new" tool from old stock, or the valve cores you are working with are of a shape or condition we couldn't account for.

    One thing to try is to put a drop of clean vacuum pump oil in the hole at the end of the tip, and then put a valve core into the tip to work the oil into the gaskets. If this doesn't improve the function on new valve cores (that is, corroded cores are problematic no matter what), then send me a message and we'll get you taken care of.
    Thank you very much! i will try that tomorrow and let you know what happens

    Is it the weird fatter core where you can see the spring around the stem?

    You might notice that the AV760 is wirelessly sending its readings to the smartphone... you might also notice that it is measuring from atmosphere and down. And for accuracy, well... I think you'll appreciate it.

    While I don't have an official launch date, stay tuned, it's almost here.

    Looks to be a hefty absolute pressure sensor possibly

    It's accurate at atmosphere (760,000 is average micron level at sea level, but we're at altitude, so we're anywhere from 630,000-650,000). It's also accurate at 15 microns.

    I know its not the greatest vacuum gauge but I really like the convenience of using my FP AVG2 vacuum gauge head and a wireless transmitter so I can be working finishing things up on an a/h somewhere and keeping an eye on the evacuation thru a meter with the wireless receiver. That would be great to have the reliability of something along the same caliber as the Bluevac with wireless monitoring. I'd grab one up for sure. Hopefully it wont be tooooo steep in price......: P

    Well maybe BlueVac is working on this as we speak.

    I spoke to Accutools twice last Tuesday and it was mentioned during one conversation that they were working on new products but who knows what??

    Yes those are annoying, that's the one I ran into on a York I did recently, just on the suction side though. I don't know why those are getting used.
