Know before you buy
You should replace the O-ring if you notice water leaking from the filter tank clamp area or if the existing rubber appears cracked, flattened, or brittle. Replacing it during your annual filter cleaning is a proactive way to prevent unexpected leaks.
No, this specific part is designed for the Clean & Clear Plus, FNS Plus, and Quad DE filter lines. Always verify your specific filter model number before purchasing to ensure a proper fit.
Installation is straightforward and typically requires no specialized tools. It is highly recommended to apply a thin layer of silicone-based pool lubricant to the new O-ring before installation to ensure a proper seal and prevent the rubber from pinching or drying out.
This is a genuine Pentair replacement part, manufactured to the exact specifications required for your filter's performance and safety standards.
While it may be tempting, O-rings lose their elasticity over time due to chemical exposure and pressure. Once a filter tank has been opened, it is best practice to install a new O-ring to guarantee a watertight seal and avoid the hassle of reopening the tank if a leak develops.
