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

Thanks

I used this tool and it worked excellent.

I got two, makes my job a lot easier when recovering/pulling vacuums and charging units and I can definitely feel the quality at work when dealing with some of the troublesome Schrader valves.

High quality tool, delivers on the job.

Great product!

There are new toys on the market but blue isn’t exactly my favorite color, way too expensive (ironic, I know). The best tool is the one you got that will do the job, and I can’t be any more happier with it. Super easy to service, has a magnet on the end to hold the valve core away from the floor or where your moving around, serviceable, and it works extremely well. Quality build by looking at it alone, using it is even better, and moreover it’s a true vacuum rated tool. Awesome!

The one they sent me leaks, am having a new one sent out so hopefully better the second time around. Using it to evacuate line set for home heat pump. Allows my vacuum pump to pull down a good deep vacuum, and the digital vacuum gauge shows this, but as soon as i closed the valve to isolate the system and gauge from the vacuum pump, the vacuum started decreasing. I thought it was my vacuum gauge at first but i confirmed with a known good one, and they both have this issue. If you do buy this, and care enough to make sure it can hold a deep vacuum, i suggest the following. 1. make sure to use a vacuum rated sealant on all connections. Nylog Blue seems to be the popular favorite. 2. using as few connections as possible from your vacuum pump, hook up your vacuum gauge to this tool, making sure the valve is between gauge and pump. 3. pull vacuum and see how low it will go after a few minutes. Mine got down around 50 microns. 4. with vacuum pump still running, close valve to isolate gauge. You may see a small rise, but it should not continue to raise too far. If it does, check your connections a few times, as this is important. If after that there is still an issue, the valve may be defective. 5.Do this before you are pumping down a system, and it will save you a ton of time in troubleshooting. Hopefully the replacement will be just fine, but i will make sure to follow my own advice and test it right out of the package before relying on it to be vacuum rated.

On second use it would not allow for vacuum to pull below 1200 microns. Highly disappointed

the product might work for others, but I have used it and have too much trouble trying to get the valve core out. its useless to pull a vacuum with this tool.

Very good quality. So far, works well.
