It transitions from a 4-inch nominal inlet to a 2-inch nominal outlet using a hub end style on both connections, allowing solvent-welded joints to PVC DWV pipe and fittings. The all-PVC construction keeps the fitting lightweight, corrosion-resistant, and compatible with standard solvent cement joining methods. Licensed plumbers and pipefitters install this coupling during new construction and remodel work where reducing the drain line diameter is required.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial DWV applications, including branch drain reductions, stack transitions, and fixture drain tie-ins. The hub end style accepts standard PVC DWV pipe and is joined using a two-step primer and solvent cement process per manufacturer and code requirements. It is manufactured domestically and meets the dimensional standards expected for Schedule 40 DWV PVC fittings used in gravity-drain systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 4-inch nominal DWV pipe down to 2-inch nominal in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHub end style on both ends for solvent-welded PVC connections\u003c\/li\u003e\n  \u003cli\u003ePVC construction resists corrosion and chemical attack from typical drain waste\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture\u003c\/li\u003e\n  \u003cli\u003eDesigned for gravity-flow drain, waste, and vent service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 4-inch by 2-inch nominal PVC DWV piping systems using hub-end solvent-weld connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the applicable plumbing code, such as the IPC or UPC. Shut off water supply and ensure the drain line is empty and dry before cutting into existing piping. Clean and deburr pipe ends, apply PVC primer followed by solvent cement to both the pipe and hub, and seat the pipe firmly with a quarter-turn twist. Allow adequate cure time before restoring flow as specified on the solvent cement product labeling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 x 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV (Drain, Waste, Vent)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K010050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51523593470258,"sku":"PDWVCOUP42","price":19.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bbf26652e67b2329d92c027a5ee1313_0828ad26-97f8-465b-a73a-0739db108182.jpg?v=1785443097","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-k010050-dwv-reducing-coupling-4x2-in-pvc","provider":"Voomi Supply","version":"1.0","type":"link"}
