Fabricated from galvanized steel, it resists corrosion and holds up in both conditioned and unconditioned spaces. The oval profile allows the fitting to fit in tighter cavities compared to round duct of the same cross-sectional area, making it a practical choice in framed wall and floor joist installations. Licensed HVAC technicians and sheet metal installers use this type of fitting to change airflow direction while maintaining system static pressure balance.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for supply or return trunk-to-branch transitions where a 90-degree directional change is required. The vertical orientation indicates the elbow transitions airflow in the vertical plane. At 5 inches, it is a common size in residential forced-air systems and light commercial applications. It is typically installed as part of a ducted distribution system connected to an air handler, furnace, or rooftop unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree turn angle for precise directional airflow routing\u003c\/li\u003e\n\u003cli\u003eOval shape allows installation in space-constrained framing cavities\u003c\/li\u003e\n\u003cli\u003eGalvanized steel construction provides corrosion resistance and long service life\u003c\/li\u003e\n\u003cli\u003eVertical elbow orientation for transitions in the vertical plane\u003c\/li\u003e\n\u003cli\u003eSmooth interior profile supports minimal airflow resistance through the bend\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 5-inch oval duct systems in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling equipment before working on the duct system. Secure all joints with approved fasteners and seal with UL-listed duct sealant or metal tape to prevent air leakage. Do not use standard cloth duct tape as a permanent sealant.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Oval\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrientation\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LUKJAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ox5405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51620364583218,"sku":"OX5405","price":17.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ea11a030a13eabfdcba9dfe988244ba.webp?v=1787342409","url":"https:\/\/voomisupply.com\/products\/lukjan-ox5405-5-inch-90-degree-oval-vertical-elbow-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
