O-ring for Dolphin C-500 canister filter
The o-ring for the Dolphin C-500 canister filter is a key sealing component that helps the filter maintain proper pressure and prevent any unwanted leaks. This o-ring sits between the main filter head and the body, ensuring that water moves through the filtration system the way it should, without escaping or reducing flow.
Over time, o-rings can become worn, flattened or less flexible due to regular use and cleaning. When this happens, the filter may start dripping, lose suction or produce inconsistent water flow. Replacing the old o-ring with a correctly sized C-500 o-ring restores a tight seal and brings the filter back to stable, reliable performance.
Made from strong, aquarium-safe rubber, this replacement o-ring is designed specifically to fit the Dolphin C-500 model. It installs easily and is an essential spare to keep on hand for routine maintenance or when servicing the filter.
Suitable for both freshwater and marine aquariums, this o-ring supports healthy tank conditions by helping your canister filter run efficiently and consistently.
