It connects 4-inch clay pipe to 3-inch plastic or cast iron pipe using a flexible sleeve secured by two stainless steel clamps. The flexible construction compensates for minor misalignment and pipe-end irregularities common in repair and retrofit scenarios. Licensed plumbers and experienced pipe installers use this coupling when transitioning between legacy clay sewer lines and modern PVC or ABS runs, or when connecting to existing cast iron drain piping.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for residential and light commercial plumbing repair work, particularly in older properties where clay tile sewer laterals are still in service. It performs in below-grade and at-grade installations and handles the pipe-size reduction from 4 inches to 3 inches in a single fitting. Typical use cases include sewer lateral repairs, building drain transitions, and service replacements where full pipe replacement is not practical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces 4-inch pipe to 3-inch pipe in one fitting\u003c\/li\u003e\n\u003cli\u003eFlexible sleeve accommodates minor misalignment and pipe-end irregularities\u003c\/li\u003e\n\u003cli\u003eTwo stainless steel clamps included for secure, corrosion-resistant connection\u003c\/li\u003e\n\u003cli\u003eJoins clay pipe to plastic (PVC, ABS) or cast iron pipe\u003c\/li\u003e\n\u003cli\u003eNo special tools required beyond a standard clamp screwdriver or nut driver\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to connect 4-inch clay pipe to 3-inch plastic or cast iron pipe as stated by the manufacturer.

Before installing, shut off any active flow and ensure pipe ends are clean, deburred, and free of sharp edges that could damage the flexible sleeve. Slide the coupling over the pipe ends, confirm full seating of both pipes into the sleeve, and tighten the stainless steel clamps evenly. Work must comply with applicable local plumbing codes and IPC standards for drain and sewer connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Connection Size (Inlet)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Connection Size (Outlet)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamps Included\u003c\/strong\u003e: 2 stainless steel clamps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Materials\u003c\/strong\u003e: Clay, Plastic (PVC, ABS), Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 40 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: 20\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 INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P1002-43\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51524027547954,"sku":"P1002-43","price":166.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/628e8b2e2cb722aecddb8c4086568644.jpg?v=1785444789","url":"https:\/\/voomisupply.com\/products\/fernco-inc-p1002-43-flexible-reducing-coupling-4x3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
