This coupling provides a reliable, gasketed connection without requiring hub ends, making it a standard solution for drain, waste, and vent (DWV) piping transitions. At 6.38 pounds, it is sized for use in larger-diameter drain lines and is typically installed by licensed plumbers working on residential or commercial plumbing systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for 12-inch diameter no-hub pipe connections in below-grade, above-grade, and in-wall DWV applications. It accommodates transitions between plastic pipe materials and cast iron, covering common field conditions where dissimilar pipe types must be joined. The Calder shielded design provides uniform compression around the pipe circumference for a secure, leak-resistant seal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-inch diameter connection for large-bore DWV drain lines\u003c\/li\u003e\n  \u003cli\u003eJoins plastic or cast iron pipe to plastic or cast iron pipe\u003c\/li\u003e\n  \u003cli\u003eCalder shielded coupling design provides uniform gasket compression\u003c\/li\u003e\n  \u003cli\u003eNo-hub installation eliminates the need for hub-end pipe fittings\u003c\/li\u003e\n  \u003cli\u003eSuited for drain, waste, and vent piping in residential and commercial systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation coupling for 12-inch no-hub plastic and cast iron DWV pipe systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off flow and drain the line before cutting into any existing drain system. Use a torque wrench calibrated to the coupling manufacturer's specified band-clamp torque range as marked on the hardware, and tighten clamps evenly. Inspect the neoprene gasket for proper seating before final tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Plastic or Cast Iron x Plastic or Cast Iron (No-Hub)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Style\u003c\/strong\u003e: Calder Shielded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 70288705690\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: MR56 1212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MISSION RUBBER","offers":[{"title":"Default Title","offer_id":51396420075826,"sku":"MR56 1212","price":53.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834550.png?v=1782831516","url":"https:\/\/voomisupply.com\/products\/mission-rubber-mr56-1212-calder-coupling-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
