The stem features an I-broach seat interface and is manufactured from brass for corrosion resistance and long service life in potable water systems. It is compliant with Vermont and California AB-1953 no-lead standards, making it suitable for installation in jurisdictions that enforce lead-free plumbing requirements. Licensed plumbers and journeymen plumbers are the primary installers for this type of faucet component.\u003c\/p\u003e\n\u003cp\u003eThis stem is suited for residential and light commercial lavatory and kitchen faucet repair work. It installs into deck-mounted faucet bodies where the Kohler 3511 hot stem has worn, stripped, or failed to seal. It ships individually on a single card, with a package quantity of six cards per case, making it practical for supply house stocking or service van inventory for shops that frequently service Kohler deck faucets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for durability and compatibility with potable water systems\u003c\/li\u003e\n  \u003cli\u003eI-broach seat interface matches original Kohler 3511 stem geometry\u003c\/li\u003e\n  \u003cli\u003eHot-side stem for proper directional valve operation\u003c\/li\u003e\n  \u003cli\u003eVermont and California AB-1953 no-lead compliant\u003c\/li\u003e\n  \u003cli\u003eSold individually per card for flexible ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct OEM-style replacement for the Kohler 3511 hot deck stem in lavatory and kitchen faucet assemblies.

Shut off the water supply and relieve line pressure before removing the existing stem. Inspect the faucet body seat for wear or damage before installing the replacement stem, as a damaged seat will prevent proper sealing regardless of stem condition. Do not overtighten the stem packing nut, as brass threads can be damaged by excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroach Type\u003c\/strong\u003e: I Broach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHot or Cold\u003c\/strong\u003e: Hot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Lavatory and Kitchen Deck Faucet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Compliance\u003c\/strong\u003e: Vermont and California AB-1953 No Lead Compliant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 per case, 1 per card\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.14 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Larsen Supply Co.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S-521-1NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LASCO","offers":[{"title":"Default Title","offer_id":51557936169266,"sku":"S-521-1NL","price":106.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/201fe604515dc6af51d7dcd3f0054900.jpg?v=1786398871","url":"https:\/\/voomisupply.com\/products\/larsen-supply-co-s-521-1nl-hot-deck-stem-kohler-3511","provider":"Voomi Supply","version":"1.0","type":"link"}
