Could I replace the tap on my Crown 40L urn with one of these (with little fuss) - https://www.kegland.com.au/1-2inch-tap-ball-valve-with-13mm-barb-robobrew-ball-valve.html
I'd just like to try and reduce hot-side aeration when dumping from my kettle to no-chill cubes..
Provided the hole was the same or similar size it would work fine. It probably is as most boiler manufactures use the 1/2 inch thread on the taps.
I am yet to see compelling evidence that hot side aeration is a significant issue. So I dont know if this is actually necessary but these are nice ball valves and definitely having a thread you can attache stuff too is nice anyway.
