O-ring for impeller cover on Dolphin C-700, C-1000, C-1300 and C-1600

The o-ring for the impeller cover on Dolphin C-700 to C-1600 canister filters is an important sealing part that helps maintain proper water flow and overall filtration performance. This o-ring creates a tight, reliable seal around the impeller chamber, preventing leaks, pressure loss and reduced circulation inside the filter.

Over time, o-rings can become flattened, brittle or stretched from regular use, which can lead to small leaks or decreased output. Replacing the worn o-ring with the correct size for your model instantly restores the secure seal required for smooth, quiet and efficient operation.

Made from durable, aquarium-safe rubber, this replacement o-ring is designed to fit the C-700, C-1000, C-1300 and C-1600 models precisely. It installs easily and is a simple but essential part of routine filter maintenance. Keeping a spare o-ring on hand helps prevent downtime and ensures your aquarium system continues running at its best after each cleaning cycle.

Suitable for both freshwater and marine environments, this o-ring supports stable tank conditions by helping your filter maintain strong water movement and dependable filtration.
