This fitting connects two different pipe diameters within a single-wall corrugated drainage system, maintaining flow continuity where pipe sizing changes. High-density polyethylene construction provides resistance to corrosion, soil chemicals, and moisture. Plumbers and drainage contractors install this coupling in residential and light commercial subsurface drainage applications where a reduction in pipe diameter is required at a junction point.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for storm drainage, yard drainage, and foundation drainage systems that use single-wall corrugated HDPE pipe. It is typically installed in-trench as part of a gravity-flow drainage network. The 4-inch to 3-inch reduction makes it appropriate for transitions from main drainage runs to smaller lateral lines or outlet connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 4-inch corrugated pipe to 3-inch corrugated pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003eSingle-wall corrugated HDPE construction for lightweight handling and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eDesigned for gravity-flow subsurface drainage applications\u003c\/li\u003e\n  \u003cli\u003eSnap-fit or sleeve-style connection compatible with standard single-wall corrugated pipe profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for use with standard single-wall corrugated HDPE drainage pipe in 4-inch and 3-inch diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or drainage contractor in accordance with local plumbing codes and IPC guidelines. Ensure the trench is properly graded before securing the coupling to maintain the designed flow slope. Confirm both pipe ends are clean and free of debris before seating the coupling. Do not use this fitting with double-wall or solid-wall pipe profiles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Density Polyethylene (HDPE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Wall Type\u003c\/strong\u003e: Single-Wall Corrugated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\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: ADVANCED DRAINAGE SYSTEMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 314 AA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ADVANCED DRAINAGE SYSTEMS","offers":[{"title":"Default Title","offer_id":51396376723762,"sku":"314 AA","price":18.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834412.jpg?v=1782830616","url":"https:\/\/voomisupply.com\/products\/advanced-drainage-systems-314-aa-hdpe-reducing-coupling-4x3","provider":"Voomi Supply","version":"1.0","type":"link"}
