It transitions from a 3-inch hub inlet to a 2-inch hub outlet, making it a standard fitting for reducing line size within a DWV stack or branch run. The fitting is manufactured from PVC material meeting ASTM D2665, F1498, D331, and D1784 specifications, delivering consistent dimensional integrity and chemical resistance. Smooth interior walls minimize flow restriction and resist scaling buildup. Licensed plumbers and pipefitters install this type of fitting during rough-in and repair work on residential and light commercial drain systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for DWV applications where a pipe size reduction is required inline. Its hub-by-hub end connections accept PVC pipe solvent-welded at both ends, providing a secure, permanent joint. The fitting also carries ratings for chemical and corrosion-resistant applications, broadening its use to environments where aggressive drain chemistry is a factor. It conforms to NSF 14 and UPC standards, which are commonly required by local plumbing codes across North America.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 3-inch hub inlet to 2-inch hub outlet for inline pipe size transitions\u003c\/li\u003e\n  \u003cli\u003ePVC construction resists chemicals and corrosion in DWV service\u003c\/li\u003e\n  \u003cli\u003eSmooth interior walls promote free flow and reduce scaling\u003c\/li\u003e\n  \u003cli\u003eMeets NSF 14 and UPC standards for plumbing code compliance\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASTM D2665, F1498, D331, and D1784 material specifications\u003c\/li\u003e\n  \u003cli\u003eHub-by-hub end connections for solvent-weld installation\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 residential and light commercial PVC DWV piping systems where a 3-inch to 2-inch reducing hub coupling is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified pipefitter in accordance with the applicable local plumbing code and IFGC requirements. Shut off water supply and confirm the drain system is depressurized and drained before cutting into existing pipe. Use an approved PVC primer and solvent cement rated for DWV service, applied per the cement manufacturer and ASTM instructions. Do not apply heat to make joint adjustments after solvent cement has been applied.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Pipe Increaser\/Reducer, Reducing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Hub x Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: ASTM D2665\/F1498\/D331\/D1784\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV, Chemical, Corrosion Resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: NSF 14, UPC\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: 5950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51467626873138,"sku":"5950","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946715.jpg?v=1783908677","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-5950-pvc-dwv-hub-coupling-reducer","provider":"Voomi Supply","version":"1.0","type":"link"}
