Sight Glass Mod


#1

Hello first time threader here at Robobrew. Does anyone know what size hole is used for the ball valve?


#2

It’s a standard 1/2" fitting. The hole itself is around 21mm diameter.

Update
I bought a sightglass from Brew international.com
It fits in the ball valve hole without a problem and no leaks. So, no drilling nessesary. Also the sightglass fitting will accept the Robobrew ball valve.

Nice find. Is that the 16" sightglass from brewinternational.com?


#5

Yes it is from Brew international.com

Nice find for a sight glass. How did you attach it at the top? It looks alot like the Fermentap sight gauge i have seen online and was thinking about getting. But your source has a much better price that others i have seen.
Cheers
