The Fluval Rim Connector, Clips & O-Rings for FX2, FX4 & FX6 is the genuine rim connector assembly for Fluval's FX canister filters, supplied with three clips and two O-rings — the bracket that holds the intake and output tubes over the tank rim.

Key Features

• Fits the Fluval FX2, FX4 and FX6 canister filters
• Supplied as a rim connector with three clips and two O-rings, which is the whole assembly rather than a single piece
• This is the part that gets snapped when a tank is moved or a hose is pulled
• Made by Fluval, the aquatics brand of Rolf C. Hagen, which has been building aquarium filters since 1975

Fitting It

• Unplug anything electrical before putting your hands in the tank
• Disconnect the hoses and take the unit to a sink rather than working over the tank
• Check the old part against the new one before fitting. If they differ, stop and check the model number
• A smear of silicone lubricant on an O-ring before reassembly makes the next service much easier and helps the seal sit properly
• Prime the filter and watch the first few minutes of running for leaks before you walk away

Good To Know

• Check the rim thickness of your tank. The connector has to clamp over it properly or the intake will move
• A loose rim connector lets the intake shift, which changes the flow and can uncover the strainer
• A smear of silicone lubricant on an O-ring before reassembly makes the next service much easier and helps the seal sit properly
• A genuine Fluval spare part. Check the model number against your unit before ordering — Fluval part numbers look alike and do not cross over between series
• Fluval sells these individually so a filter can be repaired rather than replaced, which is usually the cheaper and greener option
• Keeping a spare impeller and O-ring in the cupboard saves a tank when something fails on a weekend
