Restore a factory-tight seal on your IntelliFlo3 VSF pump with the Pentair 356189Z Lid O-Ring. This genuine Pentair gasket is precision-molded to sit flush against the pump lid sealing surface, blocking air infiltration and water escape that can compromise priming and hydraulic output. Formulated from a flexible, chemical-resistant elastomer, the O-ring maintains its shape and sealing pressure through continuous exposure to chlorinated water, heat, and UV light.

Key Benefits

• Factory-Grade Seal Restoration: Molded to exact Pentair tolerances for the IntelliFlo3 VSF pump lid, this O-ring delivers a flush, gap-free fit that eliminates air and water leaks.
• Stops Costly Water Loss: By maintaining a complete perimeter seal, this gasket prevents drips and weeping at the lid joint, conserving water and reducing chemical demand.
• Chemical and Heat Resistant: Engineered from a premium elastomer compound that resists degradation from pool chemicals, temperature fluctuations, and prolonged sun exposure.
• Consistent Pump Operation: A properly sealed lid keeps your pump fully primed, supporting steady flow rates and protecting the motor from the strain of running dry.
• Proactive Maintenance Part: Replacing the lid O-ring at regular intervals prevents gradual seal failure, safeguarding pump internals and extending the overall service life of your equipment.
