The Fluval Intake/Output Replacement Kit for 307/407 Canister Filters (A20052) is a complete, original plumbing set designed to restore and maintain the performance of your Fluval 307 and 407 Performance Canister Filters. Over time, intake and output components can become clogged, worn, or brittle, and replacing them with this kit helps ensure consistent flow, quiet operation, and reliable filtration for your aquarium.

This kit is suitable for the Fluval 307 (A446) and Fluval 407 (A449) Performance Canister Filters, making it ideal when upgrading, refreshing an older installation, or replacing lost or damaged parts. It is also compatible with earlier 06-series equivalents via the unified 06/07 plumbing design, offering flexibility for users who have transitioned between models.

What is included

The kit contains all key parts needed for the water intake and return lines on a 307/407 canister filter, making it especially helpful for beginner aquarists who prefer a ready-to-use solution.

• AquaStop valve for quick, drip-free disconnection of hoses during maintenance.

• Intake stem, intake strainer, and hose connector to safely pull water from the aquarium without drawing in fish or debris.

• Output nozzle to return clean, filtered water back to the tank with controlled direction and gentle flow.

• Motor head gasket to help maintain a proper seal and reduce the risk of leaks at the filter head.

• Aquarium rim connectors (x2) for secure positioning of hoses over the tank edge.

• Suction cups (30 mm x4 and 40 mm with clip x1) to keep intake and output pipes firmly in place and reduce vibration.

Benefits for beginner aquarists

This replacement kit is particularly suitable for new aquarists because it simplifies setup and maintenance of the filter’s plumbing.

• Provides a complete matching set of parts, removing the guesswork of selecting individual fittings.

• Restores optimal flow rate, improving mechanical, biological, and chemical filtration efficiency in Fluval 307/407 systems.

• Designed to work seamlessly with stock Fluval hoses, reducing the risk of leaks, air intake, or unstable connections.

• Clear, intuitive layout of parts makes it easier to follow standard Fluval installation and priming guides for first-time users.

Basic installation guidance

The Fluval Intake/Output Kit is designed for straightforward installation and is accessible even to aquarists with no prior experience of canister filters.

• Position the canister filter below the aquarium, ensuring hoses will run smoothly up to the tank without sharp bends.

• Connect the intake assembly (intake stem, strainer, hose connector) and fix it with the supplied rim connector and suction cups near the back corner of the aquarium.

• Attach the output nozzle on the opposite side or along the rear panel to promote even circulation and surface agitation.

• Use the AquaStop valve to connect the hoses to the filter head, and follow the standard Fluval priming procedure before switching the filter on.
