That the right nut. Put that over the spindle (inlet tube) on the regulator and it takes up the extra threads of the Swivel connection. Now you can attach a standard hose or an angled connector.
Before doing that, one needs to remove the o-ring on inlet tube that is next to the housing. That o-ring provides the seal between inlet tube and the comfort swivel hose. Not removing it will not cause any issues other compressing it for no good reason and not having it if the comfort swivel hose is put on another reg and it leaking.
