You can add a separate gauge using a duotight tee but it you want gauge built in you need the inline regulator with gauge.

Sure - you just need the right duotight fitting to go to the gauge. I have one on a T to use for spunding/priming pressure monitoring.

While not having used it for beer flow I would think it will work since it handles CO2 gas perfectly (Spunding valves) with its smaller molecules. It would be easy to clean with its few parts. Perhaps sending an email to Kegland would give the definitive answer.

Yes the Doutight in-line regulator does control flow and can lower the pressure to the tap. However I could not get the beer to stop foaming at the tap.

I tried it for that purpose and it didn’t work. It creates too much foam there are other products to control flow on the market that should do a better job.

Unfortunately we cannot provide replacement collar parts at this time. We apologize for the inconvenience.

The regulator controls pressure entering your keg. The spunding valve controls pressure leaving your keg. The regulator makes sure your keg is never below a set pressure. The spunding valve makes sure your keg is never above a set pressure. They do different jobs and are not interchangable.
