Valve Core Removal Tool Proper Use

[@sanitymaintenance1585]

I picked one of these up and have never used one before. Worked well for me on our old Trane unit . Replaced 2 out of 3 leaky cores that were bad . Taking my time about 15 minutes on both . We are still running R22 so it was a must on getting the tool and replacing the cores ,

[@askbjornmusic]

The isolation valve isolates only the back end port but not the side port so is there a good tactical way of removing a micron gauge from it before cracking the system. Currently I just take it off and some air gets sucked in and I vacuum for another few minutes before cracking. I tried using another valve on the side to isolate the gauge from the core removal tool but couldn't always get a good vacuum with them. Love the tool though. Any advice would be really helpful, cheers.

[@APECK636]

What happens with the small amount of air that is in the chamber behind the ball valve where you go to put the core back? Especially if the system is in a vacuum. Would it be better practice to put a positive charge in the system with cores removed first?

[@Appiontools]

Yes, it would be better practice to put a positive charge into the system with the cores removed first. We recommend charging the system to roughly 5 psi. The AV760 can handle this low positive pressure just fine. Once you have the system charged to 5 psi, then you can put the cores back in, remove the vacuum gauge and core tool, and continue the charge as normal. Great question!

[@ren3081]

@@Appiontools if this tool is originally designed to change cores in fully charged systems, well over 5 psi, why would you only advise to only let 5 psi out then put the cores in and then finish the charge. Couldn't you just let it all out first and then put the cores in??

[@Appiontools]

@@ren3081 It's much easier to push the stem against 5psi, also with the lesser pressure, you can get a better tactile feel when the core engages the system port threads. But its totally personal preference. We have people that will put the full charge in every time then put the cores in. Some people find a little trouble with the full charge so this is just one way not necessarily THE ONLY way.

Can you use nylog instead of vacuum pump oil?

[@richieschmidt6225]

Yes

[@akamegakill8903]

Question you use the valve core removal tool when vacuuming do also need to use it when charging

[@Appiontools]

Its best practice to use a chargning-T or a core depressor tool. Because of the accuracy needed when charging, the ability to depress the core more or less is vital. Removing the core would take that control away in most scenarios.

[@f1reguy587]

Im looking into getting these currently, noone has one in NZ, but theres alot of machines that the valve is in the wrong place to suit this fitting, ideally i would want a 45 or 90 degree female that i could attach then depress the core, i could see that being possible with a taper pushing the depressor down on a tee type fitting, cant find one though.

[@dcmarvelunited5529]

Do you recommend charging the unit with the valve core removed or with the valve core installed?

[@Appiontools]

We recommend charging the system with ≈5psi then putting the cores back in and finishing off the charge with a Charging-T or similar charging fitting. However you can fully charge the system then put the cores back in, it's not incorrect. We just find it easier to push against 5psi rather than the full charge. The main idea is to not insert your cores while still in a vacuum.

What's the secret to catching the Schrader... I've used this tool and had crushed gaskets. They don't grab and feel like a regular Schrader tool why?

[@jaydee2620]

Out of curiosity when did the 2nd generation start being produced ?

[@Appiontools]

They starting hitting shelves by the masses in early 2019

[@arodandjeter1]

Do you guys warranty directly? Or do I need to see the supplier? I bought the mega flow kit with micron gauge as shown in the video. I can't pull a vacuum under 1500 microns. Have tried many times. I have tru blu hose kit as well and have no problems pulling 500 vacuums.

Me too mine keeps leaking

[@luislopez6055]

Hi I accidentally broke the Schrader valve that’s on the side where you hook up your vacuum gauge to and is stuck on there will the tool still be usable or do I need to get it fixed

[@Appiontools]

You'd definitely want to get this repaired. Any damaged component of the tool could lead to a leak.

[@luislopez6055]

@@Appiontools and what procedures do I need to take to get this repaired?

[@Appiontools]

@@luislopez6055 We sell a full rebuild kit for our VCRTs. The KTMV25 has caps, ball valve seals, valve cores, and O-rings to replace any and all components. Here is the link to the full walkthrough of the repair. kzbin.info/www/bejne/fXmliYx_o6eIaqc

@@Appiontools ok I will look into that and what size are the valve cores for this tool?

[@matttzzz2]

Mine keeps leaking! I even bought a new one and that now leaks a few weeks later! I take meticulous care of them with regular cleaning

Sir How about the quick removal tool how to use it ..

[@chinoballa760]

Can you guys please add a valve to the side port every tech will appreciate it

[@AquaTech225]

Anyone here know if one of these is made for vehicle tire valve stems

[@Appiontools]

Technically the stem could grab the core but the threading on the tool is not made for tire valve stems.

[@lionheartchannel5842]

Thanks for sharing this video so nice tutorial.

[@avivepatterson292]

Is it possible to vacuum the system using the Appion tool without removing the core?

[@Appiontools]

I mean, it is possible but it will be SIGNIFICANTLY slower. Leaving the valve core in can reduce airflow to .2 CFM. Unless there is a specific reason that you MUST keep the core in, take the cores out.
