Review on 🔧 Wadoy R410A Valve Core Remover & Installer Tool for HVAC Systems by Ryan Arthur

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 thrown in the box, maybe for something other than a total loss. However, this is not suitable for the intended purpose of the tool.
