GBG Tap Seal - Bottom Cap
This is the bottom red rubber seal. If you notice that your machine is leaking/dripping from tap, this is most likely the part that needs replacing.
This part is said to look like a mushroom shape. It gets inserted into the white plunger piston.
This part suits the older GBG models with the white piston plunger that has a rubber O-ring and Bottom Tap Seal.
The Bottom Tap Seal appears as the bottom seal which gets inserted into the plunger (as seen in the picture above).
