Use this sanitary pressure and vacuum relief valve to help ensure pressure and vacuum do not exceed the design tolerance of the 3-in-1 and 4-in-1 conical fermenters. Factory set to release pressure and break a vacuum.
Connects to a 1.5" tri-clamp compatible port. (Not to be used in place of a blow of hose as it may plug with krausen/protein produced during the fermentation process. Before each brew ensure valve is working and free of sediment.)
