Where do the green bushings go?

They are extra gaskets. Just a different color. The ones installed are white. When they wear out you can install the green ones.

Does this shut off at the core or is it just another valve for the meters ?

These connect to your system at the Schrader valves and by turning the handle it will depress/open the Schrader valves. This opens your line set to whatever you connect on the open port on its side: * A vacuum pump * Gauge set * Micro meter * Leak tester * Refrigerant * or a combination of these. Once done with your maintenance or measurements, loosen the red or blue handle, reseating the Schrader valve, closing your system. When I used these for a new system install, I had to tighten the stem seat more than I thought I should to get the vacuum level below 500 microns. That said, I did get the system below 300 microns. So successful for the one and only time I used these.

Can i leave these on my high side service valve all the time or will the weather eventually tear them up? My high side is tough to get to.

These are used to depress the schrader core while servicing the unit. Actually to minimize the Freon release when the thumb screw gets hung, and I also use them to pull the Freon out of the high side back into the suction side when done with the servicing to clear the hoses. That is after I turn off the high side then open the gauge set to have it cross flow to the low side. You must make sure the yellow or center hose is sealed off, or capped.
