🔧 Wadoy R410A Valve Core Remover & Installer Tool for HVAC Systems Review

I had the entire AC system loaded with R410, it cooled down well, I tried to install the valve core and the tool exploded in my hands (less than 300psi) burning my hands and losing that entire coolant. When the package arrived it was sealed with tape so I could tell it had been used/returned. Very disappointed and very angry. Now I have to buy a different brand tool and wait for it to be sent because that tool was complete rubbish. Do not take any risks.

Bought last year but didn't use until last month. Worked great with the 410a adapter on my mini split, but after pulling the vacuum and applying the charge with the valve stem removed I was unable to insert the valve stem. The shank of the tool has been sheared and the shank mount will only rotate on the shaft if you rotate it. Had to ask one of my competitors for their removal tool to finish my job and put the valve core back in place.

Screw the tool to the fluid port and was able to start pulling the stem out, felt resistance, tried to pull the stem to remove the stem to close the valve on tool, but the handle got in the way. When I went to make sure the tool was screwed in, the whole tool fell apart. Many P-22s lost. Poor design as the entire tool is only held together by a very thin metal o-ring in a small groove. Paid about $30 with overnight delivery. I'll try to return the money or at least replace the unit in hopes…

I wanted to buy a valve core puller for almost three times the price of this one. Then I found this one. It had very high positive reviews. This worked great for me the first time. Great product and very well made. The only complaint I have is that the tool comes with a small set of Schrader valves. It was never mentioned in the description. So I ordered a $10 Schrader valve kit (25 pieces). If the description had been better and included information on the included Schrader valves, I would…

The purpose of this tool is to replace a valve in a loaded system without pumping it out. The serrated part that screws onto the connector is held in place by a small spring clip. Staying under pressure is not enough and it will detach from the body of the tool and make it fly while your port is now open. This is absolutely NOT good. Get your signature branding from the yellow jacket. On the plus side, the stock is a good way to remove the metal core, and it's an extra ball valve that can be…
