The flexible sleeve design compensates for minor misalignment and pipe movement, making it a practical solution for repair work where rigid fittings are not suitable. Licensed plumbers and pipefitters install this type of coupling on both new construction and retrofit jobs. It is a no-hub style fitting that connects without solvent weld, threading, or hot work.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial plumbing applications involving 4-inch pipe, including main drain lines, sewer laterals, and vent stacks. It is commonly used when connecting pipes of the same nominal diameter, including cast iron, PVC, ABS, clay, and other common DWV pipe materials. It is also a standard choice for repair sections where a damaged pipe segment needs to be replaced without disturbing the surrounding run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlexible coupling design accommodates minor pipe misalignment during installation\u003c\/li\u003e\n  \u003cli\u003eFits 4-inch nominal pipe diameter on both ends\u003c\/li\u003e\n  \u003cli\u003eNo-hub installation eliminates the need for solvent cement, threading, or open flame\u003c\/li\u003e\n  \u003cli\u003eCompatible with multiple pipe materials including PVC, ABS, cast iron, and clay\u003c\/li\u003e\n  \u003cli\u003eStainless steel clamp bands provide consistent compression and long-term seal integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible coupling for 4-inch nominal diameter DWV pipe systems in residential and commercial plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the applicable edition of the International Plumbing Code (IPC). Shut off flow and ensure the pipe is dry and clean before sliding the coupling sleeve into position. Tighten stainless steel clamp bands evenly using a nut driver or torque-limiting screwdriver per the manufacturer's guidelines. Do not overtighten the clamps, as this can damage 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Flexible no-hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV (Drain, Waste, Vent)\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: fernco-1056-44\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51138871722290,"sku":"FERNCO-1056-44","price":16.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532470.jpg?v=1778265018","url":"https:\/\/voomisupply.com\/products\/fernco-fernco-1056-44-flexible-pipe-coupling-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
