This reducing coupling connects 4-inch pipe to 2-1\/2-inch pipe, making it suitable for branch transitions and system reconfigurations where pipe diameter steps down. The cleaned and bagged packaging keeps the fitting free of oxidation and debris before installation, which supports consistent soldering results. Licensed plumbers and pipefitters install this type of fitting during new construction and retrofit work on potable water, hydronic heating, and general plumbing distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in residential and commercial plumbing applications where a 4-inch-to-2-1\/2-inch copper pipe transition is required. Typical install scenarios include main-to-branch reductions in water distribution, recirculation systems, and mechanical room piping. The cleaned and bagged preparation is particularly useful in clean-room or inspection-sensitive environments where fitting contamination is a concern prior to brazing or soldering.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing copper coupling: 4 inches inlet by 2-1\/2 inches outlet\u003c\/li\u003e\n  \u003cli\u003eCleaned and bagged for contamination-free storage and installation readiness\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard sweat-solder and brazing joining methods\u003c\/li\u003e\n  \u003cli\u003eSuitable for potable water, hydronic, and general plumbing piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for copper pipe systems using standard 4-inch and 2-1\/2-inch nominal copper tube sizes joined by sweat solder or braze methods.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the water system and allow all pipe to cool completely before cutting or fitting work begins. Clean all mating pipe ends and flux thoroughly before applying heat to ensure a sound solder joint. Do not overheat the fitting, as excessive heat can damage the copper and compromise joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePreparation\u003c\/strong\u003e: Cleaned and Bagged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 039923301321\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: ELKHART PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9004000CB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELKHART PRODUCTS","offers":[{"title":"Default Title","offer_id":51383754031410,"sku":"9004000CB","price":171.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673845.jpg?v=1782606392","url":"https:\/\/voomisupply.com\/products\/elkhart-products-9004000cb-copper-coupling-4x2-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
