2-Pack Pool Pump Lid O-Ring for P-entair 350013, 350013z | Fits IntelliFlo VF/VS/VS+SVRS, WhisperFlo, Challenger, Pinnacle, EQ-Series & Waterfall Pool and Spa Pump

Stop Pump Leaks Before They Wreck Your Pool DayPicture this: It's peak summer, and your pool pump suddenly loses prime. Water pools around the equipment pad, the filter pressure drops, and your crystal-clear water turns hazy. The culprit? A worn lid O-ring.Our 2-pack O-rings give you the peace of mind every pool owner craves. Precision-cut to P-entair's exact 350013 specs (5-7/8" ID, 6-3/8" OD, 0.275" thick), these seals form an airtight barrier that locks out debris and locks in pressure. Slip one into your IntelliFlo, WhisperFlo, or Challenger pump lid groove—no grease needed—and feel the instant difference: stronger suction, steady pressure, and zero drips.Why This Outlasts Generic O-Rings:Reinforced rubber withstands chlorine, heat, and wear, outperforming generic O-rings that degrade quickly.2 Pack Fewer Hassles: Keep spares in your pool shed. When a seal fails (mid-swim party or off-season), fix it in 30 seconds flat.No Guesswork Fitting: Matches 350013, 350013z, and 352600 pumps.
