Eliminate pump lid leaks with the Pentair Trap Cover Lid O-Ring 35505-1440, a factory-original sealing component built for WhisperfloXF and IntellifloXF pumps. This precision-molded O-ring sits between the trap cover lid and the pump housing, forming a watertight barrier that prevents air ingestion and water loss. Manufactured from chemical-resistant, pool-grade materials, it holds up against chlorine exposure, UV degradation, and temperature swings that are typical in pool equipment environments. Replacing a worn or cracked O-ring with this genuine Pentair part restores full pump priming capability and maintains the vacuum seal critical to optimal pump operation.

Key Benefits

• Precision Watertight Seal: Engineered for WhisperfloXF and IntellifloXF pumps, this O-ring creates a reliable, airtight seal between the trap cover lid and pump body.
• Stops Leaks at the Source: Replaces worn seals to eliminate water seepage and air infiltration, which are common causes of pump priming issues and reduced performance.
• Chemical and UV Resistant: Fabricated from pool-grade materials that resist degradation from chlorine, bromine, sunlight, and temperature extremes.
• Sustained Durability: Maintains its sealing integrity over extended periods, even under the constant compression and pressure cycles of daily pump operation.
• Restored Pump Efficiency: A proper lid seal is essential for maintaining vacuum pressure and water flow, directly contributing to the overall performance of your pump system.
