Pentair Valve O-Ring Kit [All O-Rings Included] (263054) poolparty and this Filbur FC-2763 cartridgeThis valve O ring kit includes the replacement seals needed for compatible Pentair valve service. O rings inside a valve are exposed to water pressure, chemical treatment, compression, and repeated movement, so they can eventually flatten, swell, crack, or leak. Replacing the full set together helps restore a more complete seal profile than changing only one visibly worn ring. The kit is ideal for push pull, backwash, or multiport valve maintenance
