Snap-On Master Valve Core Tool Set (R134a/ R12) ACT1297

I've been looking for a tool like this that works for the Eton valve cores. This and the Mastercool set are the only ones I could find so I went with the Snap-on kit and wanted to make a video showing what it comes with and the concept of how it works to allow you to change an ac Schrader valve without losing any refrigerant.
