After searching the internet I'm finding that most low side valves are Schrader type valves. However, this is definitely NOT a schrader; it appears to be some kind of black ball valve. Obviously, I need a new valve. I'm hoping to do one of two things:

1. Purchase an adaptor that simply screws on the top of the old valve, but has a schrader inside instead, OR

2. Purchase a replacement valve. In which case, I'll have to unscrew the old valve from the system.

Has anyone run into this issue? Does anyone know exactly which parts I need to buy?

THANKS
