It is designed to change the direction of copper tubing runs at a 45-degree angle in tight spaces where a long-radius sweep is not practical. Fabricated from copper, this fitting is well suited for HVAC refrigerant lines, plumbing supply lines, and hydronic piping systems. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting during new construction and service work where space constraints demand a compact elbow geometry.\u003c\/p\u003e\n\u003cp\u003eThis elbow is appropriate for residential and light commercial applications. It fits 3\/4-inch OD copper tubing and is used in scenarios where a direction change of 45 degrees is required within a confined chase, wall cavity, or mechanical room. The short-radius design minimizes the footprint of the fitting compared to a standard long-radius elbow, making it a practical choice in crowded piping layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree short-radius geometry for direction changes in confined spaces\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch outside diameter compatible with standard copper tube sizing\u003c\/li\u003e\n  \u003cli\u003eCopper construction provides corrosion resistance and reliable soldered joints\u003c\/li\u003e\n  \u003cli\u003eCompact form factor reduces clearance requirements versus long-radius fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting for use with standard 3\/4-inch OD copper tubing in HVAC, plumbing, and hydronic piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes, including IPC and IFGC requirements. Shut off and depressurize the system before cutting into any existing line. Use appropriate flux, solder, and a torch rated for sweat-fit copper fittings. Ensure all joint surfaces are clean and dry before soldering to achieve a leak-free connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadius Type\u003c\/strong\u003e: Short Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: KLEIN TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3\/445ce\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KLEIN TOOLS","offers":[{"title":"Default Title","offer_id":51383370416434,"sku":"3\/445CE","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674631.webp?v=1782594826","url":"https:\/\/voomisupply.com\/products\/klein-tools-3-445ce-3-4-in-od-45-degree-copper-elbow","provider":"Voomi Supply","version":"1.0","type":"link"}
