## Long description

Replacement gasket designed for Hagen Fluval canister filters, compatible with models 104/204, 105/205 and 106/206. This seal restores proper watertight connections between filter housings and lids or plumbing interfaces, helping prevent leaks and maintain correct filter operation. The gasket is intended for routine maintenance and repair of external Fluval filters to ensure reliable circulation and protect aquarium equipment from water damage.
Advantages
The gasket provides a precise fit that re-establishes a tight seal where the filter body meets the lid or hose fittings. Made from flexible, durable elastomer, it resists compression set and maintains sealing performance over repeated disassembly and reassembly. Using the correct replacement seal reduces the risk of leaks, ensures consistent low-noise operation by preserving designed water pathways, and extends the service life of the filter by preventing unintended water exposure to motor and electrical components.
Suitable for
 Routine maintenance of Fluval external canister filters (models 104/204, 105/205, 106/206)
 Repairing small leaks at filter housing, lid or plumbing connections
 Restoring proper seal after gasket damage, aging or deformation
 Preventive replacement during service intervals to maintain reliable filtration
Key specifications
 Material: flexible elastomeric rubber for water-tight sealing
 Compatibility: designed for specific Fluval canister filter model interfaces (104/204, 105/205, 106/206)
 Function: restores watertight seal between filter housing, lid and plumbing connections
 Durability: resistant to repeated compression and exposure to freshwater aquarium conditions
How to use
Disconnect and power off the filter before starting any maintenance. Drain water from the canister to a safe level, then separate the lid from the housing following the manufacturer’s routine procedure. Remove the old gasket, clean mating surfaces with a soft cloth to remove debris and biofilm, and inspect the sealing groove for damage. Fit the replacement gasket into the groove, ensuring even seating around the entire circumference. Reassemble the lid and housing, hand-tighten clamps or fasteners, reconnect hoses and prime according to the filter manual. Check for leaks during initial operation and retighten connections if necessary.
Usage recommendations
Replace the gasket if you observe persistent dripping, visible deformation, or after several years of service as part of preventive maintenance. Avoid using petroleum-based lubricants; if lubrication is needed, use a small amount of aquarium-safe silicone grease. Inspect seals periodically when performing routine filter cleaning to ensure continuous, leak-free operation.
