bestmax blindcap (blind plug) | BWT FS00Y30A00

The BWT bestmax blindcap seals a filter head position where no filter cartridge is installed. BWT lists it in the operating manuals of the reverse osmosis units bestaqua 14ROC COFFEE, bestaqua 14ROC ultra and bestbarista 14ROC: When replacing the membrane, first the filter cartridge bestaqua 14 PREMIUM is unscrewed clockwise from the filter head, then the blind plug is inserted into this free slot to keep the position sealed and allow the membrane to be safely replaced afterwards. BWT refers to the item under two numbers, 812162 and FS00Y30A00. When purchasing, it is only important that the thread matches the used filter head. Dimensions and material are not specified by BWT.
