Review: great product, better customer service - not only is this the best core remover on the market, I wanted to share the great customer service I got from Appion. I bought this core remover a year ago, and recently due to some idiocy, I ended up breaking the ball valve. I tried disassembling it and fixing it but couldnt get it to seal reliably. I reached out to Appion to see if they sold the ball valve and stem piece that holds it but I did not expect a response. a couple months go by and I noticed they said they would be happy to send me the pieces that were broken at no charge a couple days after I contacted them. I quickly responded back thinking that I had missed my chance, but they responded right away and shipped it out same day. HVAC specific tools are really expensive these days and you need a lot of them so having a company stand behind their products and supporting customers after purchase is such a breath of fresh air. I will probably be switching to appion for a lot of my new purchases because of this. if anyone from appion is reading this, Kara was amazing and very understanding when I failed to respond to her email for months! Review: Outstanding tool, has a superb feel to it - 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. ## Features - Vacuum Rated To 20 Microns - Easily Remove Access Valve Cores For Full, Unrestricted Flow - Double O-Ring Ball Valve Seal For Accurate "Blank Off" Vacuum Testing - Country Of Origin : United States ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 2,649 Reviews | ## Images ![MGAVCT 1/4" MegaFlow Vacuum-Rated Valve Core Removal Tool - Image 1](https://m.media-amazon.com/images/I/51er8S19ytL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does this tool have a magnetic end to hold onto cores?** A: Yes plus has pressure fit that holds the core if it's not magnetic **Q: Is it good for R410A and deep vacuums?** A: I used mine installing a mini- split 410a system. Pulled good vacuum with no issues. I don’t have manifold gauges so I added a suction gauge to this and I use it as a core remover or as a manifold. **Q: Does this tool come with seals already inside it? I received some seals with the tool and wasn’t sure if it was only for rebuilding or installing myse** A: My tool came with the seals. I didnt receive any additional seals. **Q: Is this gen 2 which has magnetic base and adjustable tip?** A: It has a magnetic base. I don't know anything about the adjustable tip. I found the tip a bit loose, so I used a plier to pinch it so the shurader valve can be hold without falling while I insert it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great product, better customer service *by T***E on April 2, 2026* not only is this the best core remover on the market, I wanted to share the great customer service I got from Appion.
