Know before you buy
This O-ring is specifically designed for Pentair Clean & Clear Plus, FNS Plus, and Quad D.E. filter models. Check your filter's manual or the existing part number to confirm it matches part number 39010200.
No, this O-ring does not come pre-lubricated. It is recommended to apply a thin, even coat of silicone-based pool lubricant to the O-ring before installation to ensure a proper seal and prevent the rubber from drying out.
Over time, O-rings can become compressed, cracked, or brittle, which leads to leaks around the filter tank clamp. Replacing it ensures a watertight seal and maintains the necessary pressure for your filtration system to operate efficiently.
No special tools are required, but you will need to loosen the tank clamp assembly to access the old O-ring. Ensure the filter system is completely powered down and the pressure is released before attempting any maintenance.
While it is not strictly required every single time, it is good practice to inspect the O-ring for signs of wear, stretching, or flattening whenever you open the tank for cleaning. If it no longer sits snugly in the groove or shows visible damage, it should be replaced immediately to prevent leaks.
