It accommodates a 6 x 4 inch nominal pipe size and features a cast iron and plastic end style, making it suited for connecting or repairing dissimilar pipe materials in a single fitting. The shielded, adjustable design allows plumbers to achieve a secure, leak-resistant connection without cutting to an exact length. Measuring 6.45 inches in diameter and 6 inches in height, this domestic-manufactured coupling is a dependable choice for repair work in residential and commercial plumbing applications.\u003c\/p\u003e\n\u003cp\u003eThis coupling is intended for use in DWV piping repair scenarios where cast iron meets plastic pipe, a common situation in older residential buildings undergoing renovation or in commercial facilities with mixed piping infrastructure. Licensed plumbers and pipefitters install this fitting when a section of existing drain or vent line requires repair or when transitioning between pipe materials during a system upgrade. Its adjustable shielded construction accommodates minor length variations, reducing the need for precise pipe cutting in tight or difficult-access locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable shielded design accommodates minor pipe length variations for easier field repair\u003c\/li\u003e\n  \u003cli\u003eCast iron and plastic end style allows transition between dissimilar pipe materials\u003c\/li\u003e\n  \u003cli\u003e6 x 4 inch nominal size suits common DWV repair applications\u003c\/li\u003e\n  \u003cli\u003e6.45 inch diameter and 6 inch height provide substantial coupling coverage\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture in the MR56 ARC series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style repair coupling for DWV piping systems where cast iron and plastic pipe materials meet at a 6 x 4 inch nominal transition point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber in accordance with applicable plumbing codes such as the IPC or local authority requirements. Before installation, shut off flow to the affected drain or vent line and ensure the pipe ends are clean, free of burrs, and properly aligned. Position the shielded coupling over the pipe ends, adjust to the correct span, and tighten the clamps evenly to achieve a uniform seal. Do not overtighten clamps on plastic pipe ends without following the manufacturer torque guidance on the coupling hardware itself.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MR56 ARC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 6 x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Cast Iron and Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Adjustable Shielded Repair Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\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: 1406073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MISSION RUBBER","offers":[{"title":"Default Title","offer_id":51620555915570,"sku":"1406073","price":149.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04711f96d1f221000cdeb2cbbaa82525.jpg?v=1787343960","url":"https:\/\/voomisupply.com\/products\/mission-rubber-1406073-mr56-arc-repair-coupling-6x4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
