Suction cups perish. They go hard, they go cloudy, and one morning the intake stem is lying on the substrate. This is a four-pack of replacement cups so you can renew a whole bracket in one go rather than nursing a single tired one. The honest caveat: Fluval uses several cup diameters across its filter ranges, so measure the cup you are replacing before you order.
If you are not sure which cup your gear takes, the rest of the range is on the Fluval collection and it is worth checking the diameter against the bracket first.
