The flapper seals the flush valve seat to control water release from the tank into the bowl during each flush cycle. This part is installed by licensed plumbers, service technicians, or experienced DIYers during routine toilet repair or water-conservation upgrades. The kit includes a foam insert, a metal chain, and a hook, giving the installer all the components needed to complete the swap without sourcing additional hardware.\u003c\/p\u003e\u003cp\u003eThis flapper is sized for 3-inch flush valve openings, which are common in higher-flow Kohler toilet models. It is suited for residential bathroom applications and is sold in individual units. The rubber construction provides a durable, watertight seal, and the included foam insert allows fine-tuning of the flush volume where the valve design supports it. Plumbers performing warranty repairs or callback visits on Kohler toilets will find this a straightforward stock item.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch rubber flapper sized for Kohler flush valve openings\u003c\/li\u003e\n\u003cli\u003eIncludes foam insert for adjustable flush volume control\u003c\/li\u003e\n\u003cli\u003eMetal chain and hook included for complete installation\u003c\/li\u003e\n\u003cli\u003eRubber construction for a durable, watertight valve seat seal\u003c\/li\u003e\n\u003cli\u003eSold individually, carded for retail or service truck stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement flapper for Kohler brand toilets equipped with 3-inch flush valve openings.

Disconnect the existing chain from the flush lever, unclip the old flapper from the overflow tube ears, and install the new 818-416 by seating the flapper ears onto the overflow tube pegs and reconnecting the chain with adequate slack. Adjust chain length so approximately one half inch of slack remains to prevent premature seal lift or a held-open valve. Follow applicable IPC guidelines for toilet repair in jurisdictions that require permitted plumbing work.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlapper Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Height\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Width\u003c\/strong\u003e: 3.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Length\u003c\/strong\u003e: 2.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 7.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 9.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PLUMB SHOP DIV BRASSCRAFT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 818-416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER PLUMBER","offers":[{"title":"Default Title","offer_id":51696413442354,"sku":"818-416","price":50.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1db82e8040b22ca7ffcc05a56bbfcadb.jpg?v=1788342395","url":"https:\/\/voomisupply.com\/products\/plumb-shop-div-brasscraft-818-416-3-inch-toilet-flapper","provider":"Voomi Supply","version":"1.0","type":"link"}
