Update: I purchased another one and selected one with some small ball valves included in the kit. I was able to determine that misunderstood how my vacuum pump worked. This particular vacuum pump leaks air back when I shut it off so the ball valve made it possible to isolate the vacuum pump from the Schrader valve removal tool. I now understand that finger tight was appropriate. I was offered a refund but I broke it and misused it so I will decline the refund.Original post:I bought this item and kept it on the shelf for 6 months waiting for the day when I complete my mini split installation. I learned that the 1/4 SAE nut is retained by a ring in a slot. If you try to eliminate leaks by tightening this beyond finger tight, you will pull the wire out of the slot in the nut and the majority of the tool risks coming off and releasing all of the refrigerant.Now for the gory details: the 1/4 inch flare body has a 7/16-20 thread and the O-ring OD is about the same as the thread dimension. The force pushing out when 300 PSI is inside the fitting is about 45 lbs.You feel this force when pushing the plunger in against the pressure. It is about 1/8 inch diameter so the force at 300 psi is 3.5 lbs.If I tighten the nut without pliers, just my rough fingers, I can produce about 20 inch pounds or about 1.66 ft-lbs. The force on the wire from my fingers is about 226 lbs which is much higher than the force produced by the pressure in the system. When I use a pair of pliers, I can achieve 10 ft-lbs which puts 1500 lbs of force on the wire and the wire squeezes out of its slot and the fitting fails.I recommend not using a pair of pliers on the knurled nut in the middle of the device. If the nut spins freely, right up to stopping, it is OK but if it is difficult to turn, the wire is out of the slot and the device is not safe to use.I need a replacement and I will look for one with a safer design so I can use pliers to over tighten it.

You can change a leaky valve core without loosing a lot of refrigerant

Easy to use. Very reasonably priced. Effective tool. Couldn’t have completed the mini split installation without it.

The last time I topped up R410a refrigerant on my 12,000 BTU, Klimaire mini-split the Schrader valve stuck open. The gauge adapter had its own valve so I left that on until this valve core tool arrived. I did lose a small bit of refrigerant while I removed the adapter and screwed on the valve core tool but not enough to worry about in the 10 seconds it took to do this. (Wear gloves, you could freeze your fingers) Once on, the tool worked perfectly, removing the defective core and replacing it with a new core with no refrigerant loss.
