This fitting creates a reliable mechanical connection where pipe sizing or system type changes within a drainage run. It is used by licensed plumbers working on residential and light commercial drain, waste, and vent assemblies. The 4-inch hub end connects to S\/D pipe while the 3-inch end connects to DWV pipe, making it well-suited for reducing transitions in gravity-flow drain lines.\u003c\/p\u003e\u003cp\u003eThis adapter coupling is typically installed in below-grade or above-grade drain and waste systems where a change in pipe diameter or pipe specification occurs between sections. Common applications include stack reductions, branch transitions, and tie-ins between different pipe specifications within a building drain system. It is appropriate for new construction as well as repair and replacement work on existing DWV assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions between 4-inch S\/D and 3-inch DWV pipe in a single fitting\u003c\/li\u003e\n\u003cli\u003eHub-style coupling design for solvent-weld installation\u003c\/li\u003e\n\u003cli\u003eSuited for gravity-flow drain, waste, and vent applications\u003c\/li\u003e\n\u003cli\u003eCompatible with standard DWV solvent cement joining methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 4-inch S\/D to 3-inch DWV pipe transitions in residential and light commercial plumbing drain systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the drain line is clear and dry before joining. Use the appropriate PVC or ABS solvent cement and primer as specified for the pipe material, and allow adequate cure time before restoring flow. Do not apply mechanical stress to the joint before the cement has fully cured.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: S\/D to DWV adapter coupling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Drain, Waste and Vent (DWV)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPEARS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPEARS","offers":[{"title":"Default Title","offer_id":51233535721778,"sku":"100-203","price":17.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307614053.jpg?v=1780102517","url":"https:\/\/voomisupply.com\/products\/spears-100203-adapter-coupling-4x3-in-s-d-to-dwv","provider":"Voomi Supply","version":"1.0","type":"link"}
