It features a chemical-resistant silicone seal that provides a durable, watertight closure and resists degradation from common tank cleaning tablets and water treatment chemicals. The adjustable design includes a timing cone that allows the installer to control the flush volume by varying how long the flapper stays open during each flush cycle. Licensed plumbers and experienced DIYers install this part as a direct replacement when a toilet runs continuously or fails to flush completely.\u003c\/p\u003e\u003cp\u003eThis flapper is suited for toilet repair applications where the existing 3-inch flush valve seat needs a reliable replacement seal. The timing cone adjustment makes it appropriate for low-consumption flush valve conversions and situations where flush performance needs to be dialed in after installation. It fits most standard 3-inch toilet flush valves and is sold individually in blister pack packaging for single-unit service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChemical-resistant silicone seal resists degradation from tank tablets and treated water\u003c\/li\u003e\n\u003cli\u003eAdjustable timing cone controls flush duration and water volume per flush\u003c\/li\u003e\n\u003cli\u003eDesigned for 3-inch toilet flush valves\u003c\/li\u003e\n\u003cli\u003eSold as an individual unit in blister pack packaging\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFits most 3-inch toilet flush valves in residential and light commercial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or qualified DIYer. Shut off the water supply valve at the base of the toilet and flush to drain the tank before beginning work. Remove the old flapper from the flush valve seat pegs and disconnect the lift chain before installing the new unit. Adjust the timing cone position after reinstalling to achieve the desired flush volume, then restore water supply and confirm the flapper seats without leaking.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush Valve Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 5.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 46224036661\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OATEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K8331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OATEY","offers":[{"title":"Default Title","offer_id":68640441041202,"sku":"K8331","price":18.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e97950b9c7ccd0186d9994e4a421cbb.jpg?v=1794404405","url":"https:\/\/voomisupply.com\/products\/oatey-k8331-adjustable-toilet-flapper-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
