Molded from durable, chemical-resistant elastomer, the gasket forms a uniform barrier between the filter head and tank body to prevent air intrusion, water seepage, and pressure loss during operation. Its exact sizing supports smooth installation into the tank groove, helping maintain the stable internal pressure needed for efficient filtration. Designed for both residential and commercial systems, the O-305 helps preserve water clarity and overall filtration reliability through daily use.\u003c\/p\u003e\n\u003ch3 data-start=\"971\" data-end=\"989\"\u003e\u003cstrong data-start=\"975\" data-end=\"989\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"990\" data-end=\"1731\"\u003e\n\u003cli data-start=\"990\" data-end=\"1145\"\u003e\n\u003cp data-start=\"992\" data-end=\"1145\"\u003e\u003cstrong data-start=\"992\" data-end=\"1018\"\u003eCX250F-Equivalent Fit:\u003c\/strong\u003e Matches Hayward’s original Star-Clear sealing dimensions for secure, leak-free performance between the filter head and tank.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1146\" data-end=\"1294\"\u003e\n\u003cp data-start=\"1148\" data-end=\"1294\"\u003e\u003cstrong data-start=\"1148\" data-end=\"1177\"\u003eProtects System Pressure:\u003c\/strong\u003e Helps prevent air leaks and water loss that can reduce filtration efficiency or interrupt normal system operation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1295\" data-end=\"1448\"\u003e\n\u003cp data-start=\"1297\" data-end=\"1448\"\u003e\u003cstrong data-start=\"1297\" data-end=\"1333\"\u003eChemical-Resistant Construction:\u003c\/strong\u003e Elastomer formulation withstands chlorine, temperature shifts, and continuous pressure cycles without deforming.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1449\" data-end=\"1601\"\u003e\n\u003cp data-start=\"1451\" data-end=\"1601\"\u003e\u003cstrong data-start=\"1451\" data-end=\"1475\"\u003eEasy Groove Seating:\u003c\/strong\u003e Precision-molded profile fits smoothly into the tank channel for quick, consistent installation during routine maintenance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1602\" data-end=\"1731\"\u003e\n\u003cp data-start=\"1604\" data-end=\"1731\"\u003e\u003cstrong data-start=\"1604\" data-end=\"1631\"\u003eEnhances Filter Output:\u003c\/strong\u003e Supports proper operating pressure, improving circulation, clarity, and overall system reliability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHayward Star-Clear Filters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"3162\" data-end=\"3181\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"3182\" data-end=\"3518\"\u003eThe Aladdin O-305 Hayward Star-Clear O-Ring replaces the CX250F head seal found on Star-Clear cartridge filter systems.
