The coupling uses a shear-ring design with two stainless steel clamps to create a secure, leak-resistant connection between dissimilar or same-material pipes. It accommodates cast iron to cast iron, cast iron to plastic, and plastic to plastic transitions without special tools or solvent welding. Licensed plumbers and pipefitters install this coupling in residential and light commercial drain line repairs, new construction tie-ins, and underground piping transitions where rigid fittings are impractical.\u003c\/p\u003e\u003cp\u003eThe P1056-64 is suited for 6-inch to 4-inch reducing connections in sanitary drain, waste, and vent applications. It is commonly installed at pipe transitions where material changes occur, such as connecting older cast iron drain lines to PVC or ABS plastic piping. The flexible body absorbs minor pipe misalignment and vibration, making it a practical choice for tight spaces, trench work, and retrofit installations where rigid fittings cannot be easily maneuvered into position.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces 6-inch pipe to 4-inch pipe in a single fitting\u003c\/li\u003e\n\u003cli\u003eCompatible with cast iron and plastic pipe materials on both ends\u003c\/li\u003e\n\u003cli\u003eIncludes two stainless steel clamps for secure, corrosion-resistant clamping\u003c\/li\u003e\n\u003cli\u003eFlexible body accommodates minor misalignment and vibration\u003c\/li\u003e\n\u003cli\u003eNo solvent welding, heat, or special tooling required for installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eConnects cast iron or plastic pipe to cast iron or plastic pipe in 6-inch to 4-inch reducing configurations.

Before servicing an existing drain line, shut off the water supply and ensure the line is drained and depressurized. Position the coupling over the pipe ends, center the fitting, and tighten the stainless steel clamps evenly using a screwdriver or nut driver to the clamp manufacturer's recommended procedure. Do not overtighten clamps, as this can distort the coupling body and compromise the seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size (Inlet)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size (Outlet)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22 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\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: P1056-64\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51525054660914,"sku":"P1056-64","price":155.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60ae3f7142a3701496b8c95a6a41149_1ac8b1d2-4d3b-4f6a-a86c-12e9b4c51209.jpg?v=1785463356","url":"https:\/\/voomisupply.com\/products\/fernco-inc-p1056-64-flexible-reducing-coupling-6x4","provider":"Voomi Supply","version":"1.0","type":"link"}
