This Pentair Lid ORing 436 provides a reliable seal for pump lids and strainer covers on compatible Pentair pumps, helping prevent water and air leaks that reduce system performance. Made from tough, flexible rubber, the Oring resists chemical exposure and compression set. Replacing a worn or cracked Oring restores proper sealing and helps maintain efficient pump priming and flow.
Pro Tip
Before seating the Oring, apply a thin layer of poolsafe silicone lubricant to improve longevity and make future lid removal easier. A clean sealing surface and proper lubrication extend service life.
Installation Tips
Clean the lid sealing surface and track before installing. Lubricate the Oring lightly with poolsafe silicone lube for easier installation and improved sealing. Ensure correct orientation and check fit before running the pump.
