Follow up video on how to fix Appion https://youtu.be/lO8DauRaMyQ?si=-l0YzRl9tUJeJwZC

With appion you can squeeze the teeth together to get a proper tension on the core

C&D valve core removal tool hasn't failed me
-
very informative video. Well done!
-
With Accutools VCR I found out that main reason to failure to remove core lies in rubber gasket. If you tighten too much the tool on valve, you fail almoust every time. Removing core is best with litlle losse tightening of tool. What frustrates me is they all pretty quick lost their 20 micron rating for vacuum pulling and even leak liquid refrigerant when I filling initial refrigerant charge.

Good to know about the Fieldpiece 5/16" adapter. I usually double up the Appion if I want to isolate my micron gauge. It's little bit of a pain, but it works, and it's only slightly bulkier than the Fieldpiece 😄. Can't say I've ever had much issue with the cores falling out, but I think I did have to adjust the tension on one of them, which is easy enough to do. If I had it to do over, I'd probably grab a couple of Fieldpieces with the adapter.

I’ve found with the Appion VCRT they can be a bit of a pain to remove the core once you have it unthreaded. There’s a trick to it, loosen the tool until you start to bleed pressure then screw it back in slightly and they come up every time.
-
Have got 2x of the Navac ones, used both 1/4 and 5/16 sizes at least half a dozen times each , no issues at all so far 👌
-
I only have the first appion model for both sizes. I noticed when I remove the core, I have to back the threads out off the service port so the gasket isn’t smashed, and kinda wiggle the tool so it comes out easier, it can be a pain. Also, I’ve ran into service ports that are smashed from people over tightening the non gasketed caps, so getting the cores out is impossible😅 great review, I’m glad I’m not the only one!
-
I was using the APion As a splitter / shut-off on my Fieldpiece recovery pump, and noticed the Apion kept working Loose from the vibration 😢 so now I want to get the fieldpiece one that has a sight-glass built in.
-
Well , like Curt , you did a good demo & review as well ... Thx:hand-purple-blue-peace:
-
Great video. I use my JB a lot now but may be in the market for new ones soon. Might have to give the FP ones a try.
-
I’ve had trouble with the Appion and found that you can’t tighten the valve on the port as it squishes the oring gasket making the opening to small for the core
-
Thanks for the vid, I have a 1/4 and 5/16 from accutools. I'll stick with what I have, but if I ever need another tool, I'll try fieldpeice.
-
I've mostly used Appion. Couldn't stand the NAVAC tool that broke apart under pressure. Recently started using the JB VCRT's. I'm super interested in the Fieldpiece VCRT's. I had two Appion 1/4" VCRT lose the vacuum I was pulling after isolating the system. For whatever reason the shut off valve would over rotate and create a gap. One was older and one was brand new out of the box.
-
The amazon are the best ones!!! Hands down 😂😂😂😂 I’ll probably get the one with the sight glass
-
Are any of the core wrenches compatible with any of the other valves?
-
Your video appeared to show bias against Appion and in favor of Fieldpiece. However, it's worth noting that Fieldpiece also didn't grab on the first attempt. In my experience as someone who uses both tools in the refrigeration industry, space is a crucial consideration and sometimes the size of the Fieldpiece makes it impractical. Regarding the Appion's grabbing issue, I find that frequently pinching the ends is necessary for it to effectively grab the cores.
-
Have always had the same issue with the appions. Brand new out of the box they won't grab them. Usually end up using pressure to shoot out the cores which doesn't always work then working on a running low temp rack running under 20 psi
-
We also have the same issue with the appion core remover. Always
