It uses a rubber sleeve and 316 stainless steel hardware to create a leak-resistant, no-hub connection on 3-inch pipe. The coupling handles a working pressure of 4.3 psi and is rated for temperatures from -30 degrees F to 140 degrees F. Licensed plumbers install this fitting as part of new construction or repair work in residential and light commercial DWV piping systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for underground, in-wall, and above-slab DWV installations where no-hub cast iron pipe is used. At 3 inches on both connection ends, it accommodates straight coupling of same-size pipe runs. The unit weighs 0.35 pounds and has a compact profile measuring 4.1 inches in length, making it practical in tight chase and stack configurations. It is commonly installed by plumbers working on soil stacks, horizontal branch lines, and building drains.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch no-hub connection on both ends for straight inline joining\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel band and hardware resist corrosion in wet and underground environments\u003c\/li\u003e\n  \u003cli\u003eRubber sleeve provides a flexible, leak-resistant seal between pipe ends\u003c\/li\u003e\n  \u003cli\u003eRated for -30 degrees F to 140 degrees F service temperature range\u003c\/li\u003e\n  \u003cli\u003e4.3 psi working pressure appropriate for gravity-flow DWV applications\u003c\/li\u003e\n  \u003cli\u003eStandard installation torque of 60 inch-pounds for consistent band tightening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style no-hub coupling for 3-inch cast iron no-hub soil pipe and fittings in residential and commercial DWV systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local authority requirements. Pipe ends should be cut square, deburred, and cleaned before the rubber sleeve and band are positioned. Tighten the stainless steel band to the manufacturer torque specification using a torque-limiting screwdriver or nut driver rated for inch-pound increments. Shut off any active flow in the line and verify the system is depressurized before removing or replacing an existing coupling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3 inches (both ends)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: No-Hub (both ends)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 4.3 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -30 degrees F to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Torque\u003c\/strong\u003e: 60 inch-pounds (standard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 316 Stainless Steel and Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 970812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950058799410,"sku":"970812","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e1d237a94c5fa50914570f37f8d7644_7d5cb39f-eb95-4f7a-8aa3-94b8ddfe701a.jpg?v=1791706098","url":"https:\/\/voomisupply.com\/products\/midland-industries-970812-no-hub-coupling-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
