It features a patented shield design that maximizes pressure transfer from the clamps to the gasket and pipe, creating a secure, leak-resistant joint. This coupling eliminates the need for traditional hub-and-spigot connections, providing a faster and more reliable method for connecting cast iron pipe sections. Licensed plumbers and pipefitters install this fitting during new construction or repair work on cast iron DWV systems.\u003c\/p\u003e\n\u003cp\u003eThe fernco-nh33 is suited for residential and light commercial plumbing applications where no-hub cast iron pipe is used. Its standard-duty NH Series construction makes it appropriate for underground, in-slab, and above-grade cast iron drain and waste piping. The patented shield distributes clamp pressure evenly around the gasket, reducing the risk of gasket distortion and joint failure common with older hub-and-spigot configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch nominal size fits standard no-hub cast iron pipe\u003c\/li\u003e\n  \u003cli\u003ePatented shield design maximizes clamp-to-gasket pressure transfer\u003c\/li\u003e\n  \u003cli\u003eReplaces hub-and-spigot connections with a more efficient no-hub joint\u003c\/li\u003e\n  \u003cli\u003eStandard-duty NH Series construction for residential and light commercial use\u003c\/li\u003e\n  \u003cli\u003eDomestic product meeting standard DWV plumbing requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement coupling for 3-inch nominal no-hub cast iron pipe used in residential and commercial DWV plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the pipe section is free of flow before beginning work. Align pipe ends squarely within the coupling gasket before tightening the clamp bands evenly to avoid gasket distortion. Do not overtighten clamp bands, as excess force can damage the gasket or pipe.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: NH Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Standard Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31163000\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-nh33\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51138664792370,"sku":"FERNCO-NH33","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532145.png?v=1778261407","url":"https:\/\/voomisupply.com\/products\/fernco-fernco-nh33-no-hub-coupling-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
