Aladdin identifies O-430 as the tank O-ring in its MicroClear stainless-steel DE filter kit and cross-references the application to Hayward DEX360K. Other documented fitment includes older MicroClear \/ Vertical DE stainless-steel C3000S and C4000S filter applications. This is a filter tank sealing O-ring, not a pool-cleaner gasket. Verify the filter model and original DEX360K part number before purchase because similar Hayward fiberglass and later filter designs may use a different tank O-ring.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing Hayward DEX360K filter tank O-rings\u003c\/li\u003e\n\u003cli\u003eServicing older Hayward MicroClear stainless-steel DE filters\u003c\/li\u003e\n\u003cli\u003eDocumented C3000S and C4000S stainless-steel tank applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy This Matters\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe tank O-ring seals the joint between the filter tank components where DEX360K is specified.\u003c\/li\u003e\n\u003cli\u003eA worn or damaged seal can allow water to leak from the tank joint.\u003c\/li\u003e\n\u003cli\u003eMatching the original Hayward part number helps reduce wrong-part orders.\u003c\/li\u003e\n\u003cli\u003eCorrect tank-ring selection matters because similar Hayward filter families may use different O-rings.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Signs You Need This \/ Use This When\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe existing filter tank O-ring is cracked, flattened, stretched, hardened, or missing.\u003c\/li\u003e\n\u003cli\u003eWater is leaking from the tank joint after the sealing surfaces have been inspected.\u003c\/li\u003e\n\u003cli\u003eYour filter parts diagram identifies Hayward DEX360K.\u003c\/li\u003e\n\u003cli\u003eYou are servicing an older MicroClear \/ Vertical DE stainless-steel filter that documents O-430 or DEX360K.\u003c\/li\u003e\n\u003cli\u003eThe existing ring no longer seats evenly in the filter tank sealing area.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAladdin Equipment Company\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eFilter tank O-ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eO-430\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eO-430-0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e601402122057\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHayward Cross-Reference\u003c\/td\u003e\n\u003ctd\u003eDEX360K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVerified Application\u003c\/td\u003e\n\u003ctd\u003eHayward MicroClear stainless-steel DE filter tank sealing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdditional Documented Applications\u003c\/td\u003e\n\u003ctd\u003eOlder MicroClear \/ Vertical DE stainless-steel C3000S and C4000S filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eListed Size\u003c\/td\u003e\n\u003ctd\u003e18-5\/16 in. inside diameter; 7\/16 in. cross-section\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eCompatibility \/ Fitment Notes\u003c\/h2\u003e\u003cp\u003eAladdin lists O-430 as the tank O-ring in its MicroClear stainless-steel DE filter service kit and identifies Hayward DEX360K as the corresponding OEM number.

Remove the old tank O-ring, clean and inspect the sealing groove and mating surfaces, and install the replacement without twisting or pinching it. Use only an O-ring lubricant approved for pool and spa equipment when appropriate. Reassemble and restart the filter only according to the manufacturer's instructions, and never open a filter while it is pressurized.\u003c\/p\u003e\u003ch2\u003eBuy with Confidence\u003c\/h2\u003e\u003cp\u003eBenchmark Pool Supply helps customers identify replacement filter parts by manufacturer, model, and OEM part number.
