It accepts a 7-inch oval inlet and steps down to a 6-inch round outlet, making it a common fitting in residential and light commercial HVAC distribution systems. Licensed HVAC technicians and sheet metal mechanics install this fitting when routing supply or return air from flat-oval trunk lines to round branch runs or register boxes. The hot-dip galvanization process provides corrosion resistance suited for unconditioned spaces such as crawlspaces, attics, and mechanical rooms.\u003c\/p\u003e\n\u003cp\u003eThis boot elbow is used in forced-air HVAC systems where a change in duct geometry is needed at a branch takeoff or terminal connection. It is well suited for residential new construction, renovation work, and system retrofits where round and oval ductwork must interface. The elbow configuration allows for directional changes at the transition point, reducing the need for additional fittings in tight mechanical chases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction for corrosion resistance in unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003e7-inch oval inlet transitions to 6-inch round outlet in a single fitting\u003c\/li\u003e\n  \u003cli\u003eElbow geometry allows directional change at the oval-to-round transition\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction compatible with standard HVAC duct fastening methods including screws and mastic\u003c\/li\u003e\n  \u003cli\u003eReduces fitting count by combining transition and directional change in one piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard 7-inch oval and 6-inch round duct systems in residential and light commercial forced-air HVAC installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal mechanics following applicable mechanical codes such as SMACNA duct construction standards. Secure the fitting with sheet metal screws and seal all joints with UL-listed duct mastic or foil tape to meet energy code requirements. Shut down and lock out the air handling unit before working on any section of the duct system. Do not use duct tape as a primary sealant on sheet metal connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOval Inlet Dimension\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound Outlet Dimension\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Oval to Round Boot Elbow\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: LUKJAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ob750706\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51619607281970,"sku":"OB750706","price":19.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fffb2af5ff0463999b2686e868b46f4b.jpg?v=1787332308","url":"https:\/\/voomisupply.com\/products\/lukjan-ob750706-oval-round-duct-boot-elbow-7x6-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
