The Aladdin O-469 Seal Plate O-Ring is a high-quality replacement component designed to match the original Sta-Rite U9-375 trap-cover seal. It re-establishes a tight, chemical-resistant seal between the pump’s seal plate (or trap cover) and pump housing, preventing air intrusion and water leaks. Manufactured from resilient elastomeric rubber with dimensions that match original OEM specs — typically ~6.75″ outside diameter, ~6.25″ inside diameter and ~¼″ thickness — this O-ring ensures a secure fit in Sta-Rite/Dyna-Glas, Dyna-Max, Max-E-Glas II, Dura-Glas II, and many related pumps. When installed properly, it restores optimal hydraulic performance and helps maintain stable pump priming and pressure for efficient filtration.
-

-
Tight Seal Against Leaks: Forms a watertight barrier between the trap cover and pump housing — helps prevent leaks, maintain pump pressure, and avoid air infiltration.

-
Correct Dimensions for Pump Models: With ~6.75″ OD / ~6.25″ ID / ~¼″ cross-section, it’s compatible with many Sta-Rite pumps including Dyna-Glas, Dyna-Max, Max-E-Glas II, etc.
