The hub-by-hub (H x H) end configuration accepts standard ABS pipe on both ends, allowing solvent-cement joints for a permanent, leak-resistant connection. This fitting is used in gravity-flow drainage systems found in residential and light commercial construction. Licensed plumbers and pipefitters install this coupling as part of DWV rough-in work behind walls, in floor assemblies, and in exposed drain runs.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for drain, waste, and vent applications where pipe size must step down along a drainage run. Typical uses include reducing a main stack branch to a smaller fixture drain, connecting lavatory or utility sink drains into a larger trunk line, and similar transitions in sanitary drainage systems. The fitting is intended for non-pressure, gravity-flow service as required by standard DWV system design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces a 3-inch inlet to a 1.5-inch outlet in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHub x Hub (H x H) ends accept standard ABS pipe with solvent cement\u003c\/li\u003e\n  \u003cli\u003eABS plastic construction — lightweight and resistant to common drain chemicals\u003c\/li\u003e\n  \u003cli\u003eDesigned for non-pressure DWV gravity-flow service\u003c\/li\u003e\n  \u003cli\u003eCompact reducing coupling profile for tight rough-in spaces\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 ABS DWV piping systems using standard 3-inch and 1.5-inch schedule pipe dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber in accordance with the applicable plumbing code, such as the IPC or UPC. Clean and deburr pipe ends before applying ABS solvent cement; use a cleaner and cement rated for ABS pipe. Ensure the fitting is fully seated and aligned before the cement sets, as ABS solvent joints are permanent. DWV systems must be pressure-tested and inspected per local jurisdiction requirements before covering rough-in work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hub x Hub (H x H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: ABS Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eService Type\u003c\/strong\u003e: DWV (Drain, Waste, Vent) — non-pressure gravity flow\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: ABSCOUP3112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51525333582130,"sku":"ABSCOUP3112","price":15.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e37eddf8d724461ac889528c234f83e.jpg?v=1785470847","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-abscoup3112-abs-dwv-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
