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

Really like the quality and easy to turn the valve

Best core tools I have ever owned. Easy to use. Buy 3. Use one on liquid valve, 1 on suction valve port and third on port of core tool to have a valve to close your micron gauge off with. DO NOT TRUST MINI BALL VALVES. ALL Yellow Jacket ball valves I own LEAK. Not these core tools. Ball valves work on charging hose ends to take pressure temp readings okay, but only use these core tools if you want good low micron pumps downs that hold around 250 microns.

Works pretty good. The stem puller itself won’t grab most stems if they are not metal. You may have to slightly bend it to grab the stem so it doesn’t get stuck in the valve.

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.

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 great. Does a better job holding on to the vavles than cheaper models and it doesnt leak.

Love this tool. Makes taking out cores very easy. Ive had a few others that get the job done but this one has been the best. Comes with a rebuil kit as well so you dont have to worry about buying one for if it fails. I use this all the time and it helps me to pull quick vacuums as well.

Good quality

Alot faster than leaving the Svalve in

As said, the best Ive ever used, including the more expensive brand. I have five. Three are for when you need The Big Three and two from others, verifiable as unused, from others, as back up, to which Ive never needed to do. I have done rebuilds on some, but on a maintenance schedule. As with planes, flight/usage time is not usually a convenient time.
