It features a 1-1\/4 inch by 1 inch reducing configuration with copper-to-copper (C x C) end connections, making it a direct solder-joint fitting. The close rough pattern provides a tight turn radius suited for installations where space is limited. This fitting is built for pressure service in water supply and hydronic applications and is installed by licensed plumbers working on residential and light commercial systems.\u003c\/p\u003e\u003cp\u003eThis elbow is used in copper pressure piping systems where a 90-degree directional change is needed with a simultaneous reduction from 1-1\/4 inch to 1 inch. Typical applications include domestic water supply lines, hydronic heating branch connections, and in-wall or in-slab rough-in work. The close rough design is particularly useful in tight mechanical spaces where standard-radius fittings cannot be accommodated.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast copper construction for consistent wall thickness and reliable solder joints\u003c\/li\u003e\n\u003cli\u003e90-degree close rough pattern for tight-radius turns in confined spaces\u003c\/li\u003e\n\u003cli\u003eReducing 1-1\/4 inch x 1 inch sizing eliminates the need for a separate reducer\u003c\/li\u003e\n\u003cli\u003eC x C end connections accept standard sweat-solder assembly\u003c\/li\u003e\n\u003cli\u003eRated for pressure service in water supply and hydronic piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pressure fitting for copper sweat-joint piping systems following ASTM and applicable plumbing code standards for water supply and hydronic service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber using standard copper soldering tools including a torch, flux, and lead-free solder per applicable plumbing codes such as the IPC or UPC. Shut off and drain the water supply before cutting into any existing line. Clean and flux all mating surfaces thoroughly before applying heat. Allow the joint to cool fully before restoring system pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 90 Degree Close Rough Elbow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/4 inches x 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x C (Copper to Copper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Pressure Fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B056000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539556237618,"sku":"B056000","price":61.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fd8c3ff2d6f54c1d6912d43d88556c9_5d75e2e9-b91d-4c2b-a30d-de49735413a0.jpg?v=1785843020","url":"https:\/\/voomisupply.com\/products\/nibco-b056000-cast-copper-90-close-rough-elbow-1-1-4x1","provider":"Voomi Supply","version":"1.0","type":"link"}
