It provides a leak-resistant, shear-resistant connection without the need for a hub, making it a practical choice for new construction and retrofit plumbing installations. The coupling accommodates a nominal 3-inch pipe on one end and a nominal 2-inch pipe on the other, allowing transitions between two common DWV pipe sizes. Licensed plumbers and pipefitters are the primary installers of this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial DWV applications where cast iron no-hub pipe is specified. It is commonly installed in sanitary drain lines, waste stacks, and vent piping concealed in walls, floors, or chases. The reducer configuration makes it useful when transitioning from a larger branch line to a smaller pipe run, such as connecting a 3-inch stack to a 2-inch branch or vent. Domestic manufacture supports project specifications that require domestically produced plumbing materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo-hub design eliminates the need for a hub or solvent welding during installation\u003c\/li\u003e\n  \u003cli\u003eNominal 3 x 2 inch reducer configuration for common DWV size transitions\u003c\/li\u003e\n  \u003cli\u003eCast iron end style for compatibility with standard no-hub cast iron pipe and fittings\u003c\/li\u003e\n  \u003cli\u003eStandard lightweight construction reduces overall system weight compared to heavy-duty couplings\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured to support project material specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for standard no-hub cast iron DWV piping systems with nominal 3-inch and 2-inch pipe ends.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of no-hub couplings should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and verify the pipe system is depressurized and drained before beginning work. Use a calibrated torque wrench to tighten the stainless steel clamp band to the torque value specified by the coupling manufacturer. Do not over-tighten, as this can distort the neoprene sleeve and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3 x 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Cast Iron No-Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Standard Lightweight No-Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\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: MISSION RUBBER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1803022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MISSION RUBBER","offers":[{"title":"Default Title","offer_id":51525067178290,"sku":"COUP32","price":17.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1249bb48399e8db8c6c0c058992eb15_ee2738ba-ce11-4eaf-995b-fb9be5bdbdd8.jpg?v=1785463642","url":"https:\/\/voomisupply.com\/products\/mission-rubber-1803022-no-hub-coupling-3x2-in-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
