The hub end style accepts standard PVC DWV pipe on both ends, creating a solvent-welded, leak-resistant joint. This fitting is a domestically produced component used in residential and light commercial plumbing systems. Licensed plumbers and experienced pipefitters install this type of coupling during new construction roughing or repair work on gravity-drain piping systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for drain, waste, and vent applications where a pipe size reduction is required within the drainage stack or horizontal branch lines. The 4 x 3 inch nominal sizing covers one of the most common stack reduction configurations encountered in residential construction, typically where a main 4-inch stack transitions to a 3-inch branch. It is not intended for pressure piping applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 4-inch nominal DWV pipe to 3-inch nominal in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHub end style on both ends for solvent-cement connections\u003c\/li\u003e\n  \u003cli\u003ePVC construction suited for non-pressure drain, waste, and vent service\u003c\/li\u003e\n  \u003cli\u003eDomestically produced fitting\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard PVC DWV pipe per ASTM D2665\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for PVC DWV piping systems using 4-inch and 3-inch nominal hub-end pipe.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or locally adopted plumbing codes. Shut off water supply and ensure the drain line is cleared and dry before cutting into existing piping. Use a manufacturer-approved PVC solvent cement and primer for all hub connections; do not substitute pressure-rated cement. Allow full cure time per the cement manufacturer instructions before returning the system to service.\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 3 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: K010000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524696047922,"sku":"PDWVCOUP43","price":19.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bbf26652e67b2329d92c027a5ee1313_5219e033-0e97-4e92-bdb4-c4007c8ab944.jpg?v=1785455561","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-k010000-dwv-reducing-coupling-4x3-in-pvc","provider":"Voomi Supply","version":"1.0","type":"link"}
