Very cool tool - HVAC schrader core changer

You may get Deja-vu from this video, as it's the full length (and horizontal) version of an earlier short.

Because China has a huge infrastructure, there are some very cool tools available cheaply from online sites like eBay. This is one of them.

It's a schrader valve core changer, but is designed to change the cores under pressure/vacuum in active refrigeration and air conditioning systems. Note that this tool is not intended for changing schrader inserts on car tyres/tires. I'm not sure what size of port they use. This tool accommodates 1/4" and 5/16" valves.

The extra side port is for extra functionality, including pulling vacuum or injecting refrigerant with the core removed for speed.
