It accommodates a wide range of pipe materials, making it a practical choice for repair and new installation work in drain, waste, and vent (DWV) applications. The coupling uses a shear ring and stainless steel clamps to compress a neoprene rubber sleeve around the pipe ends, forming a tight, pressure-resistant seal. Licensed plumbers and drain service technicians install this fitting where rigid couplings are impractical or where slight pipe misalignment or offset must be accommodated.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial plumbing applications involving 4-inch pipe runs. Typical use cases include connecting cast iron to PVC, ABS to cast iron, or clay to plastic in underground or above-ground DWV systems. The dimensional flexibility of the sleeve allows it to seal on pipes with minor surface irregularities, eliminating the need for perfectly matched pipe ends before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlexible neoprene sleeve accommodates minor pipe misalignment and surface variation\u003c\/li\u003e\n  \u003cli\u003eCompatible with a wide range of pipe materials including PVC, ABS, cast iron, clay, and concrete\u003c\/li\u003e\n  \u003cli\u003eStainless steel clamp bands provide corrosion-resistant clamping force\u003c\/li\u003e\n  \u003cli\u003ePart number, size, and compatible pipe materials are clearly marked on the coupling\u003c\/li\u003e\n  \u003cli\u003eNo solvent cement or special adhesives required for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible coupling replacement for 4-inch diameter DWV pipe connections in residential and commercial plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber in accordance with local plumbing codes and the IPC or applicable regional equivalent. Shut off water flow and relieve system pressure before cutting or removing existing pipe sections. Pipe ends should be cut square and deburred to ensure full sleeve contact and an effective seal. Tighten clamp bands evenly to the fitting manufacturer's recommended procedure without over-torquing, which can distort the sleeve.\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\u003eMaterial\u003c\/strong\u003e: Flexible PVC \/ Neoprene Sleeve with Stainless Steel Clamps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Pack Quantity\u003c\/strong\u003e: 40 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Case Dimensions\u003c\/strong\u003e: 18.375 inches x 16.375 inches x 16.625 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1056-44 4\"\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51138355986738,"sku":"1056-44 4\"","price":26.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305525617.jpg?v=1778254108","url":"https:\/\/voomisupply.com\/products\/fernco-1056-44-flexible-pvc-clamp-coupling-4-in-x-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
