Inlet Kit Fluval G3/G6 by Fluval (model A20253, MPN FV-2531)

The Fluval G3/G6 inlet kit is a replacement inlet assembly designed for use with compatible Fluval external canister filters. This inlet kit restores the water intake pathway and connection components needed for correct circulation and filtration in both freshwater and marine aquaria using G3 and G6 series units. The kit is intended for maintenance and repair when the original inlet shows signs of wear, leakage, reduced flow, or mechanical damage.

Advantages

This inlet kit is engineered to match the original inlet geometry and flow characteristics of Fluval G3 and G6 canister filters, ensuring proper fit and reliable water intake. Made from materials suitable for aquarium environments, it helps recover filtration performance without requiring replacement of the entire filter. The design facilitates straightforward reassembly and restores consistent water circulation and intake efficiency.

Suitable for

• Replacing worn or damaged inlet components on Fluval G3 and G6 external canister filters
• Restoring reduced water flow or intake function caused by damaged inlet parts
• Maintenance or repair tasks in freshwater and marine aquarium setups using compatible Fluval units

Key specifications

• Compatibility: designed for Fluval G3 and G6 series external canister filters
• Function: inlet assembly providing water intake connection and components
• Material properties: aquarium-safe plastics and seals suitable for freshwater and marine use
• Includes: inlet tube, connectors and sealing components required for reassembly

How to use

Turn off and unplug the canister filter and close any inline valves before removing the existing inlet assembly. Disassemble the old inlet components and clean the area to remove debris. Install the replacement inlet kit following the original component order, ensuring seals and connectors seat correctly to prevent leaks. Reconnect hoses and secure clamps or fasteners, then reopen valves and restart the filter. Check for leaks and confirm normal water flow before leaving the system unattended.

Usage recommendations

Inspect seals and O-rings regularly and replace them if signs of wear appear. During installation, avoid overtightening connectors to prevent stress on plastic components. Rinse new parts in dechlorinated water before installation and perform a brief leak and flow check after reassembly.
