Basket o-ring for Dolphin C-700 to C-1600 models
The basket o-ring for Dolphin C-700, C-1000, C-1300 and C-1600 models is an essential sealing component that helps keep your filter system running smoothly and efficiently. This o-ring ensures a tight, reliable seal inside the filter housing, preventing water bypass, pressure loss and leaks that can weaken overall filtration performance.
Made from durable, aquarium-safe rubber, the o-ring is designed for a precise fit across these Dolphin canister filter models. Replacing a worn or stretched o-ring is a simple but important part of maintaining strong water flow, consistent filtration and stable tank conditions.
This part is easy to install and becomes an immediate improvement to any filter that has begun showing signs of reduced suction, leaking around the head unit or inconsistent water output. Keeping spare o-rings on hand is a smart choice for any aquarist, especially when performing routine filter cleaning.
Suitable for both freshwater and marine aquariums, this o-ring helps your filter operate at its best and supports a healthier environment for your fish, plants and beneficial bacteria.
