It ships with two stainless steel clamps that compress a flexible elastomeric sleeve to form a leak-resistant seal between dissimilar or same-material pipe ends. Licensed plumbers and pipe fitters use this coupling for repair and retrofit work where rigid connections are impractical or where pipe misalignment exists. The coupling accommodates both cast iron and plastic pipe on either end, making it a versatile choice for transition joints in residential and light commercial plumbing.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in DWV piping applications where a 3-inch line reduces to a 1.5-inch line, such as branch connections at lavatories, utility sinks, or washing machine standpipes. It is well suited for underground, in-wall, and exposed drain line repairs where removing and re-cutting pipe is not practical. The flexible design allows for minor angular deflection and pipe offset, which is common in older cast iron systems and mixed-material installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 3-inch pipe to 1.5-inch pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003eConnects cast iron to cast iron, plastic to plastic, or cast iron to plastic\u003c\/li\u003e\n  \u003cli\u003eIncludes two stainless steel clamps for secure, corrosion-resistant clamping\u003c\/li\u003e\n  \u003cli\u003eFlexible elastomeric sleeve absorbs vibration and accommodates minor misalignment\u003c\/li\u003e\n  \u003cli\u003eNo special tools required for installation — standard clamp driver applies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible coupling for DWV piping transitions between 3-inch and 1.5-inch cast iron or plastic pipe ends in residential and commercial drain, waste, and vent systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water flow and drain the affected line before beginning work. Clean and deburr pipe ends so the sleeve seats evenly, and torque clamps uniformly to avoid sleeve distortion. Do not use this coupling on pressurized supply lines — it is rated for gravity-flow DWV service only.\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\u003eClamp Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamps Included\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: FERNCO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P1056-315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51525184422194,"sku":"P1056-315","price":87.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60ae3f7142a3701496b8c95a6a41149_28e922c8-9299-441e-ae05-809d06c2ea8a.jpg?v=1785466581","url":"https:\/\/voomisupply.com\/products\/fernco-inc-p1056-315-flexible-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
