Impeller cover (pump chamber cap) for the Hydra Filtron. Replace it if the tabs have snapped or the cover no longer seats flush — a loose cover lets the impeller wander and makes the pump noisy.
Fits the Ocean Free Hydra Filtron canister filter only. Check your model number on the canister lid before ordering — parts are not interchangeable between the 1000, 1500 and 1800 unless the option says so. Browse the rest of the Ocean Free range or all Fish Filters and Media.
