Description
Pentair Clean & Clear Plus / FNS Tank O-Ring
Replacement tank O-ring for Pentair Clean & Clear Plus and FNS pool filters.
Features
- Replacement tank seal for clamp-style Pentair filters
- Helps prevent leaks and air intrusion
- Designed for repeated service and filter maintenance
The Pentair 39010200Z Tank O-Ring is used to seal the filter tank halves on Clean & Clear Plus and FNS pool filters. Over time, exposure to pressure, chemicals, and heat can cause the O-ring to flatten or crack. Replacing it during routine service helps maintain proper system pressure and reliable filtration performance.
Pro Tip
If the filter has been opened multiple times, replace the O-ring proactively to avoid sudden leaks after restart.
