Genuine Pentair lid o-ring for the UltraFlow pump prefilter housing. Stops air leaks and maintains pump prime.

Pentair UltraFlow Prefilter Lid O-Ring (R39300600)

The R39300600 is the OEM Pentair o-ring that seals the prefilter lid on UltraFlow pumps. A worn or cracked lid o-ring causes air ingestion, which causes the pump to lose prime and run dry. This is one of the most common sources of air leaks on pool pumps. Regular o-ring inspection and lubrication with silicone grease extends its service life significantly.
