Pentair PacFab FNS Retainer

This retainer, part number 192194, is designed specifically for the Pentair PacFab FNS series. To ensure a perfect match, verify your filter's model number against your owner's manual or the existing part label before purchasing.

Genuine Pentair parts are manufactured to the exact specifications of your original equipment. Using OEM parts ensures proper fitment, maintains the integrity of your filter assembly, and prevents potential leaks or performance issues caused by slight variations in aftermarket dimensions.

The installation is straightforward and typically does not require specialized tools. As long as you are comfortable accessing your filter tank and securing the internal components, you should be able to complete the replacement during your routine maintenance.

You should inspect the retainer if you notice it has become brittle, cracked, or if it no longer holds the filter grids securely in place. If the retainer fails to maintain proper tension, your filter may not operate at peak efficiency, potentially allowing debris to bypass the filtration system.
