Fluval rubber connector for FX series (model A20228) – flexible hose coupling for external aquarium filters

Fluval rubber connector A20228 is a flexible hose coupling designed for use with Fluval FX series external aquarium filters. It creates a watertight join between intake/discharge tubing and the filter housing, helping to maintain proper flow and reduce the chance of leaks. The part is intended as a replacement connector for installations where the original coupling is worn, damaged or needs to be removed for maintenance.

Advantages

This rubber connector provides a secure, flexible connection that accommodates slight misalignment between hoses and the filter body while dampening vibration transfer. Made to fit the FX series connection geometry, it restores proper sealing and helps prevent water seepage at critical joints. Its flexible material simplifies removal and reinstallation during routine cleaning or part replacement.

Suitable for

• Repairing or replacing worn or damaged hose connections on FX series external filters
• Establishing watertight joins during filter installation or reassembly
• Temporary or permanent hose connections where vibration damping is desired
• Maintenance tasks that require disconnection and reconnection of tubing

Key specifications

• Material: flexible rubber compound designed for aquatic use
• Compatibility: designed to match Fluval FX series external filter connection geometry
• Function: creates watertight hose-to-housing seal and reduces vibration transfer
• Form factor: short flexible coupling suitable for standard aquarium tubing used with FX filters

How to use

Turn off and unplug the filter before attempting to replace the connector. Drain water from the tubing area as necessary to avoid spills, then carefully remove the old connector from the filter housing and tubing. Slide the Fluval rubber connector onto the tube and press it firmly onto the filter inlet or outlet until a secure seal is achieved. Reconnect any clamps or retainer parts that secure the hose in place, refill and prime the filter according to the manufacturer's instructions, then restore power and inspect the connection for leaks.

Usage recommendations

Inspect the connector periodically for signs of wear, hardening or cracking and replace it if any compromise to the seal is noted. Use only connectors compatible with the FX series to ensure proper fit and sealing. When reinstalling hoses, ensure they are pressed fully onto the fitting and, if applicable, secure with hose clamps to prevent accidental disconnection.
