I've lost a rubber washer which is located in coupler and keeps water leaks when connecting the coupler to adapter.
It looks like #17 in your diagram 2, but I'm not sure this washer is the right one.
ANSWER Hello David. Yes, based on the information you provided, 16123 is the correct rubber washer. Hope this helps.
