Key features
- Holds the lid tight against its O-ring (the rubber seal ring), so the canister stays sealed.
- Hand tightened: Fluval's FX manual says not to use tools, as they may damage the unit.

Care
Fluval's FX manual says the lid is properly closed when it is in direct contact with the canister. If the lid still leaks with good fasteners, check the lid O-ring for damage or debris.
