Appion MGAVCT 1/4 MegaFlow Vacuum-Rated Valve Core Removal Tool

Great idea, and the end removes for full bore evacuation. Had a few shreader cores I could not remove. May have to bend the ends down some. Unscrewed but just would not slide out, with pressure. Overall made very well.

Overall quality product however the side access port isnt welded in place or part of the molded body. I have 3 of these one was backup for if my orings went bad and i didnt have any backups on the roof or what not thank God i had a backup that day. I guess i over tightened my micron guage and snap goes the side port lost my vaccum a days work. And lost my backup. They are very good but could use a better side access port.

It essentially works. I prefer my older model, honestly. The newer ones seem to have a catch that keeps the Schrader from smoothly sliding out, and the core grip doesnt grab as firmly. Once you get the core out, or when replacing, it works great.

BUT I got this for evacuation, and I found that with it seated properly that it was leaking under vaccuum preventing me from pulling one. After I took it out of the loop I was able to pull the system down pretty well. Im going to get some Nylog and see if I cant get it to pull vaccuum, I was able to pull a good vaccuum with this before, but the most recent event makes me feel a little skeptical.

Fast shipping and as advertised. This Appion core removal its vacuum rated and the quality of this tool is amazing, very very low loss at the time of connection/disconnection. A++

I ordered (2) MGAVCT 1/4 on 10/12/2019. I was hesitant to order because I have seen many complaints about not being able to remove the valve core reliably. I dont know if Appion redesigned the extractor, or if I am just lucky, but both of mine grip and remove the valve core just fine. Just be sure to apply a firm pressure to the pushrod, to grip the core, before unscrewing the core. Instructions are also included that explains how to squeeze the pushrod fork tighter, using pliers, if you want an even tighter grip. However I see no need to do this since the grip seems plenty strong enough without adjustment. Also these seem to hold a vacuum just fine, aside from some small outgasing which occurs on most valves and flexible hoses.

Wow

Excelente accesorio para remover los núcleos.

Thanks

Worked just as advertised. Changed bother high and low side valves in about 5 minutes.
