It is designed for kitchen, bar, and laundry sink applications where a reliable, corrosion-resistant drain assembly is required. The removable standpipe measures 6.625 inches standalone and 5.25 inches when assembled, allowing straightforward removal for cleaning and maintenance. A 1.5-inch outer diameter tailpiece measuring 4 inches in length fits standard residential drain rough-in configurations. An included O-ring rubber stopper seats firmly to prevent leaks and maintain drainage performance. Licensed plumbers and qualified installers handle this fitting in new construction and replacement work.\u003c\/p\u003e\u003cp\u003eThe LK373 is suited for residential and light commercial sink installations including kitchen sinks, bar sinks, and laundry sinks. The removable standpipe design is particularly useful in utility and laundry room applications where the standpipe must be cleared for cleaning or serviced periodically without disturbing the drain body. The 3.5-inch drain opening and 1.5-inch OD tailpiece align with standard sink knockouts and trap arm configurations common in residential plumbing systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 304 stainless steel body and tailpiece for corrosion resistance in wet environments\u003c\/li\u003e\n\u003cli\u003eRemovable standpipe design simplifies maintenance and cleaning access\u003c\/li\u003e\n\u003cli\u003eStandpipe measures 6.625 inches standalone, 5.25 inches assembled\u003c\/li\u003e\n\u003cli\u003e1.5-inch OD tailpiece, 4 inches in length, fits standard residential drain connections\u003c\/li\u003e\n\u003cli\u003eIncluded O-ring rubber stopper provides a leak-resistant seal\u003c\/li\u003e\n\u003cli\u003e3.5-inch drain opening fits standard kitchen, bar, and laundry sink configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade drain fitting for residential kitchen, bar, and laundry sinks with a 3.5-inch drain opening and standard 1.5-inch drain outlet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and ensure the sink basin is empty and dry before beginning work. Do not overtighten the drain locknut against the sink deck, as this can crack sink material or distort the drain flange. Verify the O-ring is seated correctly before completing the assembly to ensure a proper seal at the stopper.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrain Opening Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTailpiece Outer Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTailpiece Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandpipe Length (standalone)\u003c\/strong\u003e: 6.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandpipe Length (assembled)\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody and Tailpiece Material\u003c\/strong\u003e: Type 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStopper Type\u003c\/strong\u003e: O-ring rubber\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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELKAY RESIDENTIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LK373\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELKAY","offers":[{"title":"Default Title","offer_id":67911234814258,"sku":"LK373","price":186.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f80b64b0d5680ce2e706ab77922d7bc.jpg?v=1791207342","url":"https:\/\/voomisupply.com\/products\/elkay-residential-lk373-sink-drain-removable-standpipe","provider":"Voomi Supply","version":"1.0","type":"link"}
