Appion Magaflow is a must have in your tool bag. I use two of these when I pull vacuum on my systems.
Reviewed in the United States on November 21, 2025 by Harley UltraRider-NC
I'm new to this, but I'll tell you what (I think) I've learned about this tool. Don't think of it as a Valve Core Removal Tool, think of it as your access point into your sealed system. Removing the valve core is a necessary part of that, but the purpose of this tool is to provide the two male 1/4" ports. The side port is always connected to the system and provides an all-metal (won't leak under vacuum) 1/4" connection for your thermocouple micron gauge, and the rear port connects to your 1/4" hose to your manifold. Vacuum your system down through your manifold, watching your progress on your side-mounted micron gauge. Then close the ball valve on this tool and your micron gauge is still reading system vacuum, while your hoses and manifold are out of the picture. This valve is vacuum rated to 20 microns, now you understand why that is important. This is the MGAVCT which has a female 1/4" connection to the system, the MGAVCR has a female 5/16" connection to the system and the same two 1/4" (side and back) ports. Note that if your micron gauge doesn't tolerate pressure you'll need something like a YJ 69067 ball valve to isolate it before you start adding refrigerant. (I think I've read the YJ 69075 doesn't like more than a few PSI) From the moment you get the recloseable clamshell packaging, everything about this tool feels like quality. All metal, great weight and feel, and really nice knurling. It comes with two spare o-rings, and instructions for buying a rebuild kit and parts should you ever need it. Packaging says "Parts and products made in Taiwan, USA, EU, and South America". The only thing that could improve this tool would be if it said "Made in USA" on it.

Holds a vacuum, tested down to 20 micron, valve seals and doesn’t leak when turning. Seems like a quality product.

Very, very high quality. Did not leak and that's the most important thing. I do prefer the AccuTool valve over this one but you really can't go wrong with this one

Easily removed 3 of 4 valve cores with no issues. The 4th one was getting caught by the inlet o-ring, evidently a known issue of being too thick and easily squeezed. The core was also being caught on the edges of the ball valve (a few thousandths smaller bore needed). The ball valve handle and magnet screws were coming off on both tools the first time I used them. There’s no reason they couldn’t have used a drop of blue sealer on all the screws. And lastly, one tool came with a magnet cracked into 3 pieces. Fortunately Amazon has 30 for $10 that only need a few pieces of tape to space then to the correct thickness. For being 3x more than the other CRTs, I was surprised by all the shortcomings

So I have a cheaper product that is made to do with this one is, however they do not fit the same, I find that this brand is made to fit in Tighter spaces, and you can put it at angles that are more likely for the real world if that makes sense I assume if you're here you know exactly what I'm talking about, but anyway go with this one, is constantly but it is better for hard to reach spaces, it works like a charm, it's not bulky, and this is in your pocket no problem if that's what you're trying to do with it

Despite the fact that this part (see photo) looks and is made completely differently from the one on the Appion website, the product is very well-made and works excellently. It holds a deep vacuum, nothing gets in the way, and it removes and installs the core under pressure without any issues. Overall, even if we assume that this is not an original Appion product but a clone, it definitely does not fall short in quality compared to the original. I am satisfied.
