• Function: connects filter inlet/outlet hoses to the filter unit ensuring sealed flow
• Material: durable polymer suitable for aquarium water contact
• Connection type: push-fit/insert style matching Fluval hose coupling geometry
• Usage environment: suitable for freshwater and marine aquarium systems

How to use

Turn off and unplug the filter and disconnect power before beginning any maintenance. Depressurize the system by removing tubing or opening the appropriate valve, then remove the old connector from the hose and filter port. Inspect hoses and clamps for wear and trim hose ends if necessary to ensure a clean fit. Insert the replacement connector firmly into the hose and engage the filter port connection, securing with the original hose clamps or clips. Reassemble the tubing, prime the filter if required by the model, restore power, and verify that water flow is normal and there are no leaks at the connection.

Usage recommendations

Inspect hose condition and clamps whenever replacing the connector; replace hoses or clamps showing cracks, brittleness, or corrosion. Test the connection after installation and monitor for the first 24 hours to confirm there are no slow leaks. Use only compatible hose diameters and avoid overtightening clamps to prevent deformation of the connector or hose.
