Appion MGAVCR Mega Flow Vacuum Rated Valve Core Removal Tool – 5/16" System Connection

Very good quality tool, a must have for a mini split install or repair. You must remove that valve core to get a good deep vacuum. And in my case, I also had a leaky valve core, I had to replace that valve core. This tool made the job easy.

Very well built. All the connections seem to seal. Functions smoothly. Should last awhile

Nice tool, well made, and saves time !!

Using on a mini split installation; works great, doesn't leak.

Good

Work great once I was able to the valve closed it was struck open took a 30 minute to get to finally close then it worked good except the sniffer valve had hard time getting it to go into the tool had to file the grove to fit but otherwise it was great.

No vacuum leaks. The cheap ones I bought before all were unnecessary trouble. Should have bought this one instead of wasting time and effort because of those cheap ones I had bought before. This is one of those items where you really need to buy the best tools or else you'll cuss about trying to find leaks you shouldn't have. This is the best tool that you really need, you'll forget that it cost more than the others anyway. Buy this one.
