Pentair FNS Filter Band Assembly

No, this specific assembly is designed exclusively for Pentair FNS D.E. filter systems. It is not a universal part, so please verify your filter model number before purchasing to ensure a proper fit.

The band assembly is critical for maintaining the structural integrity of your filter tank under high pressure. Using a genuine Pentair OEM part ensures the metal gauge, bolt threading, and tension capabilities meet the exact safety specifications required for your specific filter housing.

You should replace the band if you notice visible corrosion, stripped threads on the bolt, or if the band no longer maintains a tight seal around the tank halves, which often manifests as persistent leaks. If the metal appears warped or cracked, it is no longer safe to operate and should be replaced immediately.

Yes, this is a complete band assembly, which typically includes the band itself and the necessary tensioning hardware to secure the tank halves. It is designed as a direct replacement, allowing you to swap out your old, compromised unit with this new one.

This is generally a straightforward DIY task, but it requires caution because the filter tank is under pressure. Ensure the pump is off and the system is fully depressurized before attempting any work, and be sure to lubricate the tank O-ring during reassembly to ensure a proper seal.
