It uses a flexible elastomeric sleeve to create a watertight, shear-resistant connection between dissimilar pipe materials and sizes. This type of coupling is a standard tool in drain, waste, and vent (DWV) repair and new construction, where pipes of different materials or diameters must be joined without solvent welding, threading, or hot work. Licensed plumbers install this coupling in residential and commercial applications alike.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for below-grade, at-grade, and above-grade DWV installations where a 6-inch concrete line meets a 4-inch pipe run. Typical scenarios include sewer line repairs, service connections, and system upgrades where concrete mains or sleeves transition into cast iron branch lines or PVC drain runs. The coupling accommodates multiple pipe materials on the 4-inch end, making it a practical single-SKU solution for jobs involving mixed pipe systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions 6-inch concrete pipe to 4-inch cast iron, PVC, copper, steel, or lead pipe\u003c\/li\u003e\n\u003cli\u003eFlexible elastomeric sleeve absorbs minor pipe misalignment and ground movement\u003c\/li\u003e\n\u003cli\u003eNo solvent, heat, or threaded connection required for installation\u003c\/li\u003e\n\u003cli\u003eCompatible with multiple pipe materials on both inlet and outlet ends\u003c\/li\u003e\n\u003cli\u003eSuitable for DWV drain, waste, and vent applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to connect 6-inch concrete pipe to 4-inch cast iron, PVC, copper, steel, or lead pipe in DWV systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber. Shut off flow and relieve any pressure or drainage load on the line before beginning work. Slide the coupling sleeves over each pipe end, seat the gasket fully against each pipe, and tighten the stainless steel clamp bands evenly to manufacturer torque guidance. Follow applicable IPC and local plumbing code requirements for underground or concealed DWV connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 6 inches (concrete)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 4 inches (cast iron, PVC, copper, steel, lead)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV drain, waste, and vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Materials\u003c\/strong\u003e: Concrete, cast iron, PVC, copper, steel, lead\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FERNCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: fernco-1006-64\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51138835284274,"sku":"FERNCO-1006-64","price":30.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532472.jpg?v=1778264418","url":"https:\/\/voomisupply.com\/products\/fernco-fernco-1006-64-flexible-pipe-coupling-6-to-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
