It accommodates transitions between cast iron and plastic pipe, or same-material connections of either type. Two stainless steel clamps are included and provide a secure, leak-resistant seal without the need for special tools or adhesives. Licensed plumbers and pipefitters install this coupling in residential and light commercial applications where rigid joining methods are impractical or where pipe alignment is slightly off-center.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for below-grade, in-wall, and exposed DWV piping. It performs well in renovation and repair scenarios where sections of existing cast iron drain lines are being tied into new PVC or ABS runs. The flexible shear ring design absorbs minor pipe movement and vibration, which is common in older structures. It is also used in new construction where mixed-material pipe systems are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConnects 4-inch cast iron pipe to 4-inch plastic pipe, or same-material to same-material\u003c\/li\u003e\n  \u003cli\u003eIncludes two stainless steel clamps for corrosion resistance and long-term clamping force\u003c\/li\u003e\n  \u003cli\u003eFlexible elastomeric body accommodates minor misalignment and pipe movement\u003c\/li\u003e\n  \u003cli\u003eNo solvent cement, oakum, or lead required for installation\u003c\/li\u003e\n  \u003cli\u003eSuitable for drain, waste, and vent piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 4-inch outside-diameter cast iron or plastic (PVC, ABS) DWV pipe.

Shut off any flow to the affected line and ensure pipe ends are clean, deburred, and free of debris before sliding the coupling into position. Tighten the stainless steel clamps evenly using a nut driver or flat-blade screwdriver to achieve a uniform seal. Do not overtighten clamps, as this can deform the elastomeric sleeve and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches x 4 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: Cast iron, PVC, ABS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 48 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 40\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: P1056-44\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51525473304882,"sku":"P1056-44","price":280.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83c162feac7ced0740a1a728d2169df2_91ceb222-b6a8-4f4c-87d3-9049f9713fc9.jpg?v=1785474822","url":"https:\/\/voomisupply.com\/products\/fernco-inc-p1056-44-flexible-pipe-coupling-4x4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
