The Fluval Intake/Output Kit for 107/207 Canister Filters (A20051) is a genuine replacement set designed to restore the original performance and safety of Fluval 107 and 207 external filters. Over time, external parts such as valves, nozzles, and seals can harden or wear, leading to reduced flow and potential leaks; this kit allows you to renew all key intake and return components in one convenient package.

Specifically engineered for the Fluval 107 (A440) and Fluval 207 (A443) Performance Canister Filters, this kit maintains correct fit, alignment, and sealing pressure, which are essential for efficient filtration and quiet operation. Because all parts are original Fluval components, you avoid the guesswork and potential incompatibilities that can occur with generic fittings or improvised hardware.

What is included

This complete kit replaces all external water‑handling parts between the canister and the aquarium.

• AquaStop valve with pre‑installed O‑rings for secure, drip‑free hose connections and quick disconnection during maintenance

• Intake stem with integrated strainer and hose connector to protect fish and shrimp from being drawn into the filter

• Output nozzle for directing clean water back into the aquarium with smooth, controlled flow

• Motor head gasket to maintain a watertight seal between the motor head and the canister body

• Two aquarium rim connectors to fix the intake and output securely to the tank edge

• Four 30 mm suction cups and one 40 mm suction cup with clip to keep intake and return lines firmly in place against the glass

These components work together to prevent vibration, reduce noise, and keep hoses neatly routed, which is especially reassuring for a beginner setting up a first canister filter.

Benefits for beginner aquarists

For a new aquarist, a leaking or poorly performing canister filter can be stressful and confusing; this all‑in‑one kit simplifies troubleshooting by refreshing all external flow parts at once. The AquaStop valve allows easy shut‑off and disconnection for cleaning without draining hoses, helping beginners perform maintenance without spills.

The intake strainer protects small fish and shrimp while ensuring debris is efficiently drawn into the filter, supporting clear, healthy water. Secure suction cups and rim connectors hold the pipework in position so hoses do not move or kink, reducing the risk of accidental splashes or loss of siphon.

Basic installation guidance

Installation is straightforward and can usually be completed in a few minutes with no special tools.

• Ensure the filter is unplugged from the mains before starting any work on the hoses or motor head.

• Close the AquaStop valve, disconnect the old hose assembly, and remove old intake and output parts from the aquarium glass.

• Fit the new AquaStop valve and hose connectors, push the tubing fully onto the fittings, and tighten collars by hand for a secure seal.

• Attach the new intake stem with strainer and output nozzle using the supplied rim connectors and suction cups, positioning them to achieve good circulation without strong currents on delicate fish.

• Replace the motor head gasket if the old seal is flattened or damaged, then reassemble, prime, and restart the filter following the standard Fluval 107/207 instructions.
