134a A/c Gauges

JUST purchased a set of 134A a/c gauges from local parts store. there is a blue and red for high and vacuum side. But there is also a yellow one ???? Now basing on the fitting, there is a valve that automatically shuts when not connected, so I'm assuming that that's where the refrigerant bottle goes. Any thoughts?
