Manufactured from chemical-resistant elastomeric rubber, it maintains flexibility under pressure, heat, and daily pump operation to prevent air intrusion and water leakage. The O-469 follows the OEM sizing profile, typically around 6.75 inches outer diameter, 6.25 inches inner diameter, and a quarter-inch cross-section, allowing it to seat securely in Sta-Rite and related pump series including Dyna-Glas, Dyna-Max, Max-E-Glas II, and Dura-Glas II. When installed correctly, it restores proper priming, stable suction, and dependable hydraulic performance for efficient filtration.\u003c\/p\u003e\n\u003ch3 data-start=\"1028\" data-end=\"1046\"\u003e\u003cstrong data-start=\"1032\" data-end=\"1046\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"1047\" data-end=\"1842\"\u003e\n\u003cli data-start=\"1047\" data-end=\"1216\"\u003e\n\u003cp data-start=\"1049\" data-end=\"1216\"\u003e\u003cstrong data-start=\"1049\" data-end=\"1073\"\u003eOEM-Spec Dimensions:\u003c\/strong\u003e Matches the Sta-Rite U9-375 and O-12 sealing profile for correct placement and leak-free operation across compatible Sta-Rite pump families.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1217\" data-end=\"1366\"\u003e\n\u003cp data-start=\"1219\" data-end=\"1366\"\u003e\u003cstrong data-start=\"1219\" data-end=\"1250\"\u003eSecures a Water-Tight Seal:\u003c\/strong\u003e Creates a uniform sealing surface that helps prevent leaks, air infiltration, pressure loss, and flow disruption.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1367\" data-end=\"1518\"\u003e\n\u003cp data-start=\"1369\" data-end=\"1518\"\u003e\u003cstrong data-start=\"1369\" data-end=\"1397\"\u003eDurable Elastomer Build:\u003c\/strong\u003e Chemical-resistant rubber withstands sanitizers, heat, and continuous pump cycles without flattening or deteriorating.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1519\" data-end=\"1703\"\u003e\n\u003cp data-start=\"1521\" data-end=\"1703\"\u003e\u003cstrong data-start=\"1521\" data-end=\"1550\"\u003eSized for Sta-Rite Pumps:\u003c\/strong\u003e Fits pump models using roughly 6.75 inch OD, 6.25 inch ID, and quarter-inch thickness, including Dyna-Glas, Dyna-Max, Max-E-Glas II, and Dura-Glas II.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1704\" data-end=\"1842\"\u003e\n\u003cp data-start=\"1706\" data-end=\"1842\"\u003e\u003cstrong data-start=\"1706\" data-end=\"1727\"\u003eEasy Replacement:\u003c\/strong\u003e Designed to seat smoothly into the trap-cover groove for quick installation during maintenance or pump reassembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSta-Rite Dyna-Glas Pumps\u003c\/li\u003e\n\u003cli\u003eSta-Rite Dyna-Max Pumps\u003c\/li\u003e\n\u003cli\u003eSta-Rite Max-E-Glas II Pumps\u003c\/li\u003e\n\u003cli\u003eSta-Rite Dura-Glas II Pumps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"3425\" data-end=\"3444\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"3445\" data-end=\"3836\"\u003eThe Aladdin O-469 Seal Plate O-Ring matches the Sta-Rite U9-375\/O-12 trap-cover seal used in Dyna-Glas, Dyna-Max, Max-E-Glas II, Dura-Glas II, and similar pumps.
