When I pulled out the gasket from my Yellow Jacket vacuum gauge coupler I didn’t have this tool, I used a knife and small needle nose pliers. Since I am still fairly new to HVAC, I didn’t realize I needed to unscrew the core depressor before trying to get out the gasket which made it even harder. This tool is sold with five quarter inch gaskets, and I was able to use the opposite end from the pick to screw in the core depressor. Next time I look forward to having the tool to remove the core depressor and the gasket. Great little tool. Thanks!
This tool is great for removing and installing quarter inch rubber gaskets in the gage end of your refrigerant hoses
