120 Degree Tight Radius Aluminum Bend 3.5in OD

The 120 Degree Tight Radius Aluminum Bend 3.5in OD is a precision mandrel-formed tube component engineered for custom fabrication, exhaust system assembly, and structural piping applications where sharp bends and tight radii are critical. This aluminum tubing bend serves mechanical engineers, fabricators, and restoration specialists who require repeatable, professional-grade bends without flattening or kinking that can compromise flow or structural integrity. Built for applications demanding both durability and aesthetic appeal, this component integrates seamlessly into performance exhaust systems, roll cage construction, and pneumatic/hydraulic installations.

This 120-degree bend features a 3.5-inch outer diameter with a tight 2.5-inch radius, precision-mandrel formed to eliminate wall collapse and maintain consistent wall thickness of 2mm throughout the bend. The 1.5-inch and 5-inch leg configurations provide flexibility in layout design, while the polished aluminum finish resists oxidation and delivers a professional appearance suitable for visible applications. Aluminum's lightweight properties—this bend weighs just 1.37 lbs—make it ideal for weight-sensitive projects without sacrificing structural reliability or pressure-handling capability in pneumatic and cooling system designs.

Fabricators, custom builders, and OEM suppliers benefit most from this tubing bend when constructing performance exhaust manifolds, intake runners, or custom air ducting systems where standard 90-degree angles prove inadequate. Installation is straightforward—the mandrel-formed structure prevents splitting or deformation during handling and assembly, eliminating the need for reinforcement sleeves or secondary reinforcement. This component integrates with standard aluminum tubing fittings and clamps, making it compatible with both TIG-welding and mechanical fastening methods for permanent or modular assembly configurations.
