Benefits

The Pentair 190003 OEM Band Clamp Kit helps keep compatible Clean & Clear Plus filter tanks properly secured during operation. Since cartridge filters operate under pressure, the clamp is a critical part of the filter assembly and should be replaced if it is damaged, corroded, stretched, or no longer tightening correctly.

Using the correct OEM Pentair clamp helps ensure proper fitment with the filter tank body and lid. This can help reduce leaks at the tank seam, improve serviceability after cartridge cleaning, and provide a more reliable closure compared to worn or incorrect hardware.

For pool professionals, this is a common replacement part to keep available for Clean & Clear Plus filter repairs. For homeowners, it is the correct replacement option when servicing compatible Pentair cartridge filters.
