Constructed from rubber, it provides a flexible, watertight transition between 3-inch cast iron and 3-inch plastic pipe. The unshielded design keeps the profile low in tight spaces while maintaining a secure seal. Plumbers and pipefitters install this coupling in residential and light commercial sewer and drain lines where a reliable, code-acceptable connection between different pipe materials is required.\u003c\/p\u003e\u003cp\u003eThe MR56-33 is suited for underground, non-pressure, and gravity-flow applications. Typical installations include connecting cast iron stack sections to PVC or ABS drain lines during new construction or remodel work, and for repair situations where an existing cast iron line must be transitioned to plastic. The flexible rubber sleeve accommodates minor pipe misalignment and outside-diameter variation common in older cast iron piping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRubber construction provides flexibility and a durable watertight seal\u003c\/li\u003e\n\u003cli\u003eJoins 3-inch cast iron pipe to 3-inch plastic pipe\u003c\/li\u003e\n\u003cli\u003eUnshielded design suits installations where a low-profile coupling is needed\u003c\/li\u003e\n\u003cli\u003eRated for underground, non-pressure, and gravity-flow service\u003c\/li\u003e\n\u003cli\u003eAccommodates minor pipe misalignment and outside-diameter variation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3-inch cast iron and 3-inch plastic (PVC or ABS) pipe in non-pressure, gravity-flow drain, waste, and vent applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off any upstream flow and confirm the pipe ends are clean, deburred, and free of debris before sliding the coupling into position. Tighten the clamp bands evenly and to the torque range specified on the coupling packaging. This coupling is not rated for pressure pipe systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Cast iron to plastic (PVC or ABS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Underground, non-pressure, gravity-flow sewer and drain\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MR56-33\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MISSION RUBBER","offers":[{"title":"Default Title","offer_id":67649710719282,"sku":"MR56-33","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/199553994.jpg?v=1790461313","url":"https:\/\/voomisupply.com\/products\/mission-rubber-mr56-33-flex-seal-sewer-coupling-3-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
