Built to HD Series specifications, it features a patented shield design that maximizes pressure transfer from the clamps to the gasket and pipe, producing a secure, leak-resistant connection. The coupling is constructed from stainless steel and manufactured domestically. It meets multiple industry standards including ASTM C564\/C1540 and CISPI 310. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications where a reliable, code-compliant no-hub connection is required.\u003c\/p\u003e\n\u003cp\u003eThe hd-33 is suited for 3-inch nominal no-hub cast iron piping systems in residential and commercial plumbing installations. It is specifically engineered to replace less-efficient hub-and-spigot connections, making it a practical choice for drain and waste line repairs or new rough-in work. The heavy-duty classification means it performs where standard couplings may be undersized for the application, such as below-slab or high-load drain runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePatented shield design maximizes clamp-to-gasket pressure transfer for a secure seal\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty construction rated for demanding no-hub cast iron piping applications\u003c\/li\u003e\n  \u003cli\u003eStainless steel body resists corrosion in wet and underground environments\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture meets ASTM C564\/C1540 and CISPI 310 standards\u003c\/li\u003e\n  \u003cli\u003eIAPMO listed (File No. 3198) and carries MEA 253-98-E approval\u003c\/li\u003e\n  \u003cli\u003eDesigned to replace hub-and-spigot joints with a more efficient no-hub connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style heavy-duty replacement coupling for 3-inch nominal no-hub cast iron pipe systems conforming to CISPI 310 and ASTM C1540 standards.\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 International Plumbing Code (IPC). Shut off flow to the line and relieve any system pressure before removing existing fittings or pipe sections. Ensure pipe ends are clean, square, and free of burrs before seating the gasket and tightening the shield clamps. Do not over-torque the clamp bolts; follow the torque range specified in the applicable CISPI 310 installation guidelines.\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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.61 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: US\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards and Approvals\u003c\/strong\u003e: ASTM C564\/C1540, CISPI 310, CMR-248, IAPMO File No. 3198, MEA 253-98-E\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: hd-33\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51138510258482,"sku":"HD-33","price":45.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305525797.jpg?v=1778258034","url":"https:\/\/voomisupply.com\/products\/fernco-hd-33-heavy-duty-no-hub-pipe-coupling-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
