Its near 10-inch inner diameter and sturdy ¼-inch cross-section allow the gasket to seat securely between mating components, forming a watertight, pressure-holding seal that helps maintain system efficiency. Built from chemical-resistant rubber, the O-240 withstands regular exposure to chlorinated and saltwater pool conditions while retaining its flexibility through repeated maintenance cycles. Compatible with equipment from major manufacturers such as Hayward, Pentair Ultra-Flow, Sta-Rite, Aqua-Flo, and similar pump and filter systems, this O-ring restores sealing integrity and supports long-term circulation performance.\u003c\/p\u003e\n\u003ch3 data-start=\"3138\" data-end=\"3156\"\u003e\u003cstrong data-start=\"3142\" data-end=\"3156\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"3157\" data-end=\"4024\"\u003e\n\u003cli data-start=\"3157\" data-end=\"3355\"\u003e\n\u003cp data-start=\"3159\" data-end=\"3355\"\u003e\u003cstrong data-start=\"3159\" data-end=\"3189\"\u003eCross-Brand Compatibility:\u003c\/strong\u003e Designed to fit various pump housings, volutes, seal plates, and filter heads used by Hayward, Pentair Ultra-Flow, Sta-Rite, Aqua-Flo, and related equipment lines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3356\" data-end=\"3540\"\u003e\n\u003cp data-start=\"3358\" data-end=\"3540\"\u003e\u003cstrong data-start=\"3358\" data-end=\"3384\"\u003eProper 10-Inch Sizing:\u003c\/strong\u003e Built to the approximate 10-inch inner diameter and ¼-inch thickness of original factory gaskets to ensure stable seating and leak-resistant performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3541\" data-end=\"3695\"\u003e\n\u003cp data-start=\"3543\" data-end=\"3695\"\u003e\u003cstrong data-start=\"3543\" data-end=\"3583\"\u003eLong-Lasting Elastomer Construction:\u003c\/strong\u003e Made from rubber engineered to tolerate chlorine, saltwater, and heat cycles without deformation or cracking.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3696\" data-end=\"3860\"\u003e\n\u003cp data-start=\"3698\" data-end=\"3860\"\u003e\u003cstrong data-start=\"3698\" data-end=\"3730\"\u003eMaintains Internal Pressure:\u003c\/strong\u003e Forms a tight, durable seal that prevents leaks and pressure loss, helping filtration systems operate smoothly and efficiently.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3861\" data-end=\"4024\"\u003e\n\u003cp data-start=\"3863\" data-end=\"4024\"\u003e\u003cstrong data-start=\"3863\" data-end=\"3900\"\u003eCost-Effective Service Component:\u003c\/strong\u003e A practical, low-cost solution for resealing pump and filter assemblies during routine maintenance or equipment rebuilds.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eStarClear\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDura-Glas\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMax-E-Pro\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMaxi-Glas\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSwimquip\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eReplacement for OEM Part Numbers\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCX900F\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e39006000\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e92200180\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e320-110\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e31-358\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eU9-228A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e35505-0422\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eO-1082\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"5890\" data-end=\"5909\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"5910\" data-end=\"6394\"\u003eThe Aladdin O-240 O-Ring features a 10-inch inner diameter and a thick ¼-inch cross-section used to seal pump housings, filter heads, volutes, and seal plates across multiple equipment brands.
