Comparing & Testing Several Valve Core Removal Tools

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

very informative video. Well done!

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.

Well , like Curt , you did a good demo & review as well ... Thx

jb one is pretty cool i have to try that one

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 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!

The amazon are the best ones!!! Hands down 😂😂😂😂 I’ll probably get the one with the sight glass

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’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.

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.

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.

C&D valve core removal tool hasn't failed me

mini splits is where the larger ones have issues because of where some put their ports

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.

in response to the appion remover that one is the second generation, there is video they have to adjust the tip.

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.

We also have the same issue with the appion core remover. Always

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

Removal tool madness

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

I just used my Appion the other day and it worked fine. It snapped on and held the core. Looks like yours isn't snapping on.

You can easily adjust the grabber on the appion vcrts with a set of needle nose pliers like it explains and shows in the instructions manual.

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.

I've bought Schrader depressors / core removal. JB / Yellow Jacket / C&D / all the gaskets eventually melt and the tools are useless. Good luck getting new gaskets in them. I've recently bought Appions. Well see if they hold up better.

I believe the Fieldpiece has the best built vctr, followed by the JB. I have Appion and Uniweld and I like the later better

I use Appion for my evacuations and reinstalling cores only, for it's vacuum rated body. Not a service tool for replacing cores under pressure. The NAVAC core tool has been ok so far

With the appion 2 things are vital 1 is that the grabber is adjusted properly which is where the grabber does click onto the core and 2 DO NOT over tighten the vcrt body to the port as if you do the inner o-ring will get squashed such that the inside clearance reduces enough to grab the core. If you have problems getting the core out with an appion try loosening the end a lil bit at a time. Until I figured that part out it wouldn't work for me. As far as the jb goes ive had 2 so far and they both leaked at the lever fresh outta the box. I gave up on those. As for the accutools I really dislike the grabber end and it hasn't worked out for me yet.

I would love the JB (torque) with a site glass. A cross between FP and JB. We should be checking the valve core torque.

I’ve been having the same issues with my appions…it always does that bs

Core removal tool? I didn’t know that even existed I just use a core tip screw driver given to me By the local supply house Just make sure area is clear put a brick in the Core path and let it rip

Appion has a video and you should pinch them or expand them every time to get a tight fit but I will get the FIELDPIECE ones just because I love FIELDPIECE

I use an extra to adjust the grabber.

I despise the Appion's never has worked in years of use....I always blow it out with the gas pressure.

I have purchased CPS core removal tools for the price there "F/N" great

i get it its just a reference but true tech tools isnt always thge best price just a fyi for other techs

I prefer my C&D, looks the same as Accutools brand, prefer over Appion which is bulkier.

I have used every single core remover on the market and eventually they all leak at some point, specially Apion

I have yellow jackets and they have trouble sometimes too. Seems like this is a hard item to design because it looks like they all have drawbacks

Appion, leaks after 3 times? Bought Yellow Jacket then.

I purchased Appion after Yellow Jacket core tool ownership. The rubber seals leaking on the YJ drove me to look at alternatives and the o-ring seals on the Appion are better. The first Appion purchase was the pink 5/16th unit and it had the stem grabbing type end. The next 1/4” Appion had the body grab style. This is a terrible design as the tolerances on cores are all over the map. Sometimes it grabs, sometimes not. I ended up using the YJ core trapper on the Appion body, as it grades on the stem. This seems like a half ass solution as they did make the stem grab type remover. Frustrating! My original 5/16 Appion are giving me vacumn fits as it seems that the ball valve is leaking and cannot be serviced by the repair kit offered. I think I may have to scrap them after spending $78 CDN on the repair kit. F*#k!ng maddening.

Man I had a Navac once, first time trying to remove one under pressure the fuckin thing literally blew apart I lost the entire charge

I love your videos, but your sponsorship is showing through.. the Appion are adjustable, the standars for cores are trash. Having a tool that allows you to adjust them in the field gives you a wide range of ability. Don’t get me wrong Fieldpeice really has come up with the work of art adding the sight-glass and isolation valves. I’ve also never had an issue with NAVAC, other than their length Which seems to be a common problem with most core tools with most mini splits. My recommendation is if you’re going to review tools take the time and do the research on how to use the tool correctly. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pb5BB8Up2Lg.htmlsi=yX0f7_y5GePIOnZ2

The appion code tools sucks, I WAS VERY VERY DISAPPOINTED IN THE INABILITY TO GRAB THE CORE AND REMOVE

After first min watching you use appion, I knew. Couldn't finished watching your "Review" , you couldn't even use it properly. Not all core are sized exactly the same. Wonder which core removal tool was paying for your "review" 😂
