Pentair WhisperFlo and IntelliFlo Lid O-Ring

Replacement lid O-ring for Pentair IntelliFlo (VF, VS 3050, VS+SVRS), WhisperFlo, Challenger, and Pinnacle pumps (350013); it also fits many WaterFall and select EQ Series models. It seals the strainer cover to the pump housing to prevent air leaks and water seepage so the pump holds prime. Also called the pot-flange/pump trap lid O-ring; apply a thin coat of silicone-based lube and seat it in the lid groove during install.
