For 'vacuum filler' fountain pens, the tip at the back (the piston knob) must always be unscrewed slightly to let the ink flow through when you write for a long time. Therefore, when the piston knob is completely screwed in, the rubber piece at the end of the metal rod inside seals the reservoir of the nib and prevents the ink from flowing to the end of it (recommended during transport or when the fountain pen is not in use).
