Sera Ceramic shaft for Sera Fil 120 E

A ceramic shaft for the sera fil 120 internal filter, five pieces per pack.

What the part does: the shaft is the rod the pump rotor turns around. Ceramic is the chosen material because it withstands constant rotation in water without wearing or rusting.

Why five of them: the shaft is thin and brittle, and it breaks most easily during cleaning. A pack of five means in practice that a spare is on the shelf even when the last one broke at the wrong moment.

Mind the model: this part is for the fil 120. The fil 60 in the same range is a different sized unit and does not use the same shaft.
