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

Excelente herramienta, la calidad y el acabado es de lo mejor, muy satisfecho con esta compra.

Im new to this, but Ill tell you what (I think) Ive learned about this tool. Dont 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 (wont 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 doesnt tolerate pressure youll need something like a YJ 69067 ball valve to isolate it before you start adding refrigerant. (I think Ive read the YJ 69075 doesnt 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.

Very handy tool for any HVAC engineer. Very high quality American made and easy to use

This tool is useless. It won’t grab the Schrader so you can unthread and remove it, and I’ve actually broken one inside the valve because this tool sucks so bad. Apion makes great recovery machines, but this tool is a complete waste of money.

Works Fine- Thanks!

Used it twice and on the third time the actual schrader removal tool while it’s under pressure kept getting stuck when trying to push it in and it wouldn’t allow the schrader to come out even tho I could feel it unscrewing. Im buying yellow jacket

Worked great. Bought a cheaper make and it would not hold vacuum as well. I think this one might have leaked a bit too but could be operator error. Relied on nitrogen pressure check to check leaks and then just triple vacuum and then open up condenser valves to charge system. Working fine.

good

Works very good- highly recommend. I used this is as a guage for the low side by connecting a single guage to the top side port.

This product works as described!
