Its metal additively manufactured 6061 aluminum body replaces a multi-piece fabricated transition, helping create cleaner, more repeatable assemblies with fewer seams.\u003c\/p\u003e\n\u003ch3\u003eButt-Weld Tube Ends\u003c\/h3\u003e\n\u003cp\u003eThe straight tube ends are designed for conventional butt welding to same-size aluminum tubing. Each end matches the nominal outside diameter of the corresponding tube size, creating a flush outside profile for fit-up and welding. The merge has a 1\/8-inch (0.125-inch) wall; the mating tube wall thickness may be selected by the fabricator for the application.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Dual 4-inch inlets to single 5-inch outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061 aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall thickness:\u003c\/strong\u003e 1\/8 inch (0.125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube-end outside diameter:\u003c\/strong\u003e Matches the nominal OD of corresponding 4-inch and 5-inch tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing process:\u003c\/strong\u003e Metal additive manufacturing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Flush-OD butt-weld tube ends\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduction status:\u003c\/strong\u003e Made to order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDesigned for Fabricators\u003c\/h3\u003e\n\u003cp\u003eThis universal component provides an engineered foundation for custom induction and charge-air systems.
