It connects a 4-inch spigot to a 3-inch hub, allowing plumbers to transition between pipe sizes within DWV runs. The fitting is manufactured from PVC conforming to ASTM D2665, F1498, D331, and D1784 material specifications. Smooth interior walls minimize scaling and support consistent flow. The flush bushing profile keeps the fitting seated flush within the hub, maintaining a clean, low-profile connection point. Licensed plumbers and pipefitters are the primary installers for this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for residential and light commercial DWV applications where a spigot-to-hub reduction is required. It performs well in environments with exposure to common drain chemicals and corrosive waste streams, making it appropriate for both standard sanitary drain lines and chemical-resistant piping layouts. The fitting meets NSF 14 and UPC standards, supporting use in jurisdictions that require certified DWV components. Where a 4-inch main line must transition down to a 3-inch branch or stub-out, this bushing provides a direct, code-compliant solution.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlush bushing profile seats cleanly within the hub for a low-profile, secure fit\u003c\/li\u003e\n  \u003cli\u003e4-inch spigot to 3-inch hub end connection for in-line pipe size reduction\u003c\/li\u003e\n  \u003cli\u003ePVC construction resists corrosion and common drain chemicals\u003c\/li\u003e\n  \u003cli\u003eSmooth interior walls reduce scaling and support unobstructed flow\u003c\/li\u003e\n  \u003cli\u003eMeets NSF 14 and UPC certification standards for DWV applications\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASTM D2665, F1498, D331, and D1784 specifications for dimensional consistency\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 PVC DWV piping systems requiring a 4-inch to 3-inch spigot-to-hub flush bushing reduction, in applications conforming to NSF 14 and UPC requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber following applicable local plumbing codes and IPC or UPC standards. Solvent-cement the spigot end into the receiving hub using a PVC-rated primer and cement appropriate for DWV service. Ensure both mating surfaces are clean, dry, and free of debris before applying cement. Allow full cure time per the cement manufacturer's instructions before restoring flow to the line.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Flush Bushing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 inches x 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Spigot 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\u003eApplicable Standard\u003c\/strong\u003e: NSF 14, UPC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV, Chemical, Corrosion\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: 5909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51468571017522,"sku":"5909","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946736.jpg?v=1783917946","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-5909-pvc-dwv-flush-bushing-4x3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
