Generic Filter O-Ring Repair Kit for the Pro Series Filters

This kit is designed to fit the standard Hayward Pro Series sand filter line. We recommend verifying your specific filter model number against the Hayward parts manual to ensure the O-ring diameters match your tank lid and valve assembly.

Yes, the kit includes the primary tank lid O-ring, which is the most common culprit for leaks at the top of the filter. It also includes the necessary valve O-rings and gaskets to address leaks occurring at the multiport valve connection.

The silicone lubricant is essential for creating a proper watertight seal and preventing the rubber from pinching or tearing during installation. Applying a thin layer also helps the O-ring seat correctly in the groove, which extends the lifespan of the seal.

It is best practice to inspect your O-rings annually when you open or close your pool for the season. If you notice any cracking, flattening, or signs of dry rot, replace them immediately to prevent unexpected leaks during peak operation.
