Oh wow, okay that's great to know. I was afraid of it shattering but I will only use about 5 PSI on it and release all the pressure in the fermenter.The sight glass will hold more psi than the PRV will permit. I’ve put 40 PSI on my sight glass to move a plug of pellet hops back up into the tank.
I am not sure if releasing all pressure in the fermenter is okay to do? I have heard of creating a vaccum if you do not add co2 during the cold crash. But once the temp is established, is it necessary to keep co2 in the vessel at all times?
