It connects a fitting-end (FTG) outlet to a copper-tube-end (C) inlet, both sized at 1-1\/4 inches. The long radius design reduces turbulence and pressure drop compared to standard-radius fittings, making it well suited for high-flow domestic water, hydronic heating, and HVAC piping applications. Licensed plumbers and pipefitters install this fitting using standard solder and flux per applicable codes. Wrot copper construction delivers consistent wall thickness and clean joint surfaces for reliable brazed or soldered connections.\u003c\/p\u003e\n\u003cp\u003eThis elbow is used in residential and light commercial plumbing and mechanical piping systems wherever a 90-degree direction change is required. The street configuration — FTG on one end — allows the fitting to be inserted directly into another fitting socket without an additional coupling, saving labor in tight or congested piping runs. Typical applications include supply and return lines in hydronic heating systems, domestic hot and cold water distribution, and refrigeration equipment piping where copper is the specified material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWrot copper construction for uniform wall thickness and clean solder surfaces\u003c\/li\u003e\n  \u003cli\u003eLong radius sweep reduces flow restriction and pressure drop at the direction change\u003c\/li\u003e\n  \u003cli\u003eStreet (FTG x C) end configuration eliminates need for an additional coupling in back-to-back fitting installations\u003c\/li\u003e\n  \u003cli\u003e90-degree angle for standard perpendicular direction changes in piping runs\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch connection size on both ends for consistent pipe sizing throughout the assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style wrot copper solder fitting for 1-1\/4 inch copper tube systems following ASTM B16.22 or equivalent standards in plumbing and mechanical piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments. Shut off and drain the affected piping system before cutting or fitting. Clean all mating surfaces with emery cloth and apply appropriate flux before soldering or brazing. Do not apply heat directly to the fitting socket for extended periods, as overheating wrot copper can cause oxidation that compromises the joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Wrot Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-1\/4 x 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FTG x C (Street)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdapter Type\u003c\/strong\u003e: Long Radius, Street\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Height\u003c\/strong\u003e: 3.66 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Length\/Depth\u003c\/strong\u003e: 3.54 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Weight\u003c\/strong\u003e: 0.42 pounds\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ELL00879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51523394404658,"sku":"ELL00879","price":41.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f32c4b76089103426046efb261ed40fa.webp?v=1785441723","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-ell00879-90-degree-long-radius-elbow","provider":"Voomi Supply","version":"1.0","type":"link"}
